Aniimo events: the full Aniimo season 1 calendar
Every Aniimo event on the official Aniimo season 1 calendar: start and end dates, the weekly Prismana rotation, and what each block actually gives you.
What went up on the official site
Aniimo put the whole of season 1 on one page. Not in a patch note, not in a dev letter — as a single graphic on the front of the official site, under a navigation entry that did not exist a week ago. The Aniimo season 1 calendar covers 16 September to 28 October along the top, and two of the bars on it run to 9 December.
This is every one of the Aniimo events on that graphic, window by window, including the Aniimo Prismana rate-up schedule — the one row that changes what you do with your week. Everything below is read off the calendar itself. Where the graphic is silent, and it is silent about more than you would expect, this page says so instead of filling the gap.
The calendar sits on aniimo.com itself, under a menu entry called Event Calendar, between Milestones and Features. It is one image, 2,250 pixels wide, and the file behind it was last touched on 13 September. There is no announcement next to it: the news centre’s Event category is still empty, and the newest post there is the pre-download notice from 14 September.

That matters for how you read it. A calendar with no text post attached carries no fine print — no reward lists, no rules, no server times. It is a schedule and nothing else. Treat it as the shape of the season rather than the terms of it.
The rows are split into two groups. New Player Events, labelled Always Open, sit at the top with no dates on them at all. Update Events fill everything below, each with a date pill in the format month-dot-day. No year is printed anywhere on the graphic, and neither is a time zone.
Two events that never close
The always-open group has two entries.
Prismana Promise: Choose Your Prismana Aniimo is the one people will ask about first, and it is the one event on the whole calendar the site actually explains. A section higher up the same page says it in one line: “Become a Junior Wayfarer to select a Prismana Form Aniimo.” So it is a free pick, gated behind a rank rather than a date. Which ones are on offer, and which is worth taking, is on our page for the free Prismana picks. What the calendar adds is only this: the bar has no end on it, so the offer is not a launch-window promotion.
Set Out, Pathfinder! is the second, and it gets the opposite treatment: a name, a bar across the full width, and nothing else anywhere on the site. The same Welfare block does mention a multi-day login reward — a Susuta egg for pre-registering, and a random Perfect Egg for logging in across several days — but it does not attach that to this bar, and neither will we.
The useful part is the label on the row: New Player Events, Always Open. Everything else on the graphic has an end date. These two do not, which means neither of them is a reason to rush on day one. If you are working out what to do first, the things worth knowing before you start are a better use of the opening hours than chasing an event that will still be there in November.
The Journey Handbook block: forty-three days
One bar sets the frame for everything under it. Journey Handbook runs 16 September to 28 October — forty-three days, start and end day included.
Every other dated bar on the calendar begins inside that window, and almost all of them end inside it too. So forty-three days is the length of the block the calendar is built around, and if you want a single number for how long the opening stretch of Aniimo runs, that is the one the graphic actually supports.
What the block does tell you is where the season’s centre of gravity sits. Every event that repeats does its repeating inside these forty-three days. Only two bars carry a date beyond them, and both are Legendary Journey rows.
Three events that rotate through it
Inside the forty-three days, three events come and go in windows rather than running continuously.
| Event | Window 1 | Window 2 | Window 3 |
|---|---|---|---|
| Who’s That Aniimo? | 16–24 Sept | 2–8 Oct | 16–22 Oct |
| Idyll Ecological Investigation | 16–20 Sept | 2–8 Oct | 16–22 Oct |
| Glamour Star | 25 Sept – 1 Oct | 9–15 Oct | 23–29 Oct |
Read down the columns and the rotation falls out. Who’s That Aniimo and Idyll Ecological Investigation share their windows almost exactly — identical in October, and in September the investigation closes four days earlier. Glamour Star takes the weeks in between. Its first window opens on 25 September, the day after Who’s That Aniimo closes; its second opens on 9 October, the day after the second pair closes.
The practical read: there is never a week in the season with none of the three running, and never a week with all three. One family is on, the other is off, and every changeover lands on a Friday.
Glamour Star is the odd one out in a second way. Its third window, 23 to 29 October, is the only dated bar in the rotation that ends after the Journey Handbook block closes on the 28th. One day past, which is either a deliberate overhang or a rounding of the season’s last week. The graphic does not explain it.
Two more bars fill the middle of the board. Aniimo Discovery: Dazmand takes a single fourteen-day window, 25 September to 8 October — one featured creature, one window, no repeat. Journey Moments starts on 1 October and runs to the 28th — the last four weeks of the Journey Handbook block rather than the whole of it.
Vein Abundance: a Prismana every week
If you plan around one row on this calendar, plan around this one. Vein Abundance is where the graphic says which name gets a featured week — and each of the five names gets exactly one window, with no second run anywhere on the board.
Vein Abundance runs along the bottom as a continuous strip, split into six blocks. The first is a location. The other five name Prismana, each with the word UP printed next to it and that creature’s artwork inside the same block.
| Window | Block | Days |
|---|---|---|
| 18–20 Sept | Forest of Falling Stars | Fri–Sun |
| 21–27 Sept | Prismana Glynsera UP | Mon–Sun |
| 28 Sept – 4 Oct | Prismana Melloblum UP | Mon–Sun |
| 5–11 Oct | Prismana Waleetle UP | Mon–Sun |
| 12–18 Oct | Prismana Inferlupa UP | Mon–Sun |
| 19–25 Oct | Prismana Carnival UP | Mon–Sun |
Five clean Monday-to-Sunday weeks, back to back, with a three-day opening weekend in front of them that is tied to a place instead of a creature.
Worth being precise about the word UP, because it is the part that gets misread. It is not a separate event. On the graphic it sits inside a named block, after the name, with the matching artwork — the red wolf sits in the Inferlupa block, the group shot sits in the Carnival block. It is the label on a rate-up window — the way a banner is labelled in any other game with a schedule like this — but the graphic never spells that out. What goes up, and by how much, it does not say. That is a real gap, not a coy one: there is no reward text anywhere on the image.
What you can take from it is the ordering, and the ordering is worth planning around. If the Aniimo Prismana you want is Waleetle, its week is 5 to 11 October and there is no second one on this calendar. Prismana Carnival, last of the five, is the only featured week that does not name a single creature — its block carries a group of them, and it closes the row on 25 October. For what a Prismana form is and which ones are handed out for free, the Junior Wayfarer picks are the place to start.
Eggceleration, and the weekend pattern
Under Vein Abundance sits Eggceleration, six short blocks with a date on each and no name at all: 18 to 20 September, 25 to 27 September, 2 to 4 October, 9 to 11 October, 16 to 18 October and 23 to 25 October.
Every one of those is a Friday to a Sunday. Six weekends, no exceptions, and no gap between them longer than four days.
Put the two rows next to each other and this is the one piece of planning the calendar hands you for free. Every Eggceleration window is the last three days of a Vein Abundance window. Glynsera runs 21 to 27 September; Eggceleration runs 25 to 27. Melloblum runs 28 September to 4 October; Eggceleration runs 2 to 4. The same holds for Waleetle, Inferlupa and Carnival. The first pair is that rule in miniature: the Forest of Falling Stars window is itself only three days long, so Eggceleration covers all of it.
So the shape of a week on this calendar is a featured name for seven days with an Eggceleration window over its last three. What Eggceleration does is not written anywhere on the image. Where it sits is — and it sits in the same place six times running.
The two events that outlast the calendar
The date axis stops at 28 October. Two bars carry a date that runs past it.
Tracing the Trail carries the pill 9.20–12.9 — 20 September to 9 December, eighty-one days. Legendary Journey: Walking with Irisalis & Gift of Blessing carries 9.25–12.9 — 25 September to 9 December, seventy-six days. Both simply run to the right-hand edge of the board, like several bars that stop on the 28th, which is why they are easy to miss on a quick look: the pill is the only place the December date appears at all.
The Irisalis bar has a handover built into it. Immediately to its left sits Legendary Journey: Trail of Butterfly Shadows, 16 to 25 September, and the two meet on the 25th — one closes on the day the other opens, in the same row, under the same Legendary Journey heading. That is the graphic’s own reading of the sequence: a short opening chapter, then a long one that carries the season.
Between them they are the two longest dated bars on the board, Tracing the Trail by five days over the Irisalis one. If the December date holds, the story side of the first season runs about six weeks past the last Vein Abundance week.
Aniimo season 1, in eight dates
Eleven dated bars is a lot to hold in your head. Stripped back to the days on which something actually changes, the whole of Aniimo season 1 comes down to eight.
16 September — the season opens
Journey Handbook, Who’s That Aniimo, Idyll Ecological Investigation and the Trail of Butterfly Shadows all start on day one
18 September — the first farming weekend
Forest of Falling Stars and the first Eggceleration window, both 18 to 20 September
20 September — Tracing the Trail opens
and does not close until 9 December, the longest dated bar on the board
25 September — handover day
Butterfly Shadows closes, the Irisalis journey opens, and Glamour Star and Dazmand both start
1 October — Journey Moments joins
runs to 28 October, the back stretch of the Journey Handbook block
25 October — the last featured week ends
Prismana Carnival closes the Vein Abundance row; no sixth Prismana window is on the calendar
28 October — the Journey Handbook block closes
the date axis stops here, and Glamour Star runs one day past it
9 December — the two long events end
Tracing the Trail and the Irisalis journey, and nothing on the graphic about what follows
Read that list and the shape of the season is obvious: a dense opening fortnight, a steady weekly rhythm through October, and a story thread that keeps going for six weeks after the farming stops.
What the calendar does not tell you
The gaps are as informative as the bars, and being straight about them is the point of this page.
No time zone. Not on the graphic, not in a caption, not in a post beside it. Aniimo’s servers all open at the same moment on 16 September — 02:00 UTC, which is 10:00 in UTC+8 and 22:00 on the 15th in UTC−4 — but the calendar makes no claim about when an event day starts or ends. Until something official says otherwise, treat a date on that graphic as a date, not as a timestamp.
No year. Every pill is month-dot-day. Read in sequence they run September to December 2026, and 12.9 is 9 December rather than 12 September, because the axis it hangs under is already past September. That is an inference, and a safe one, but it is an inference.
No rewards. Not one item name appears on the image. What Prismana Promise gives you, what an Eggceleration weekend actually multiplies, what UP raises and by how much — none of it is on the calendar, and none of it is in a post next to the calendar. What Aniimo does sell is a separate question, and one we went through listing by listing.
No second season. There is nothing on the graphic about what follows 9 December, no teaser row, no faded bar at the right edge.
Pawprint says as much itself, in small type under the rewards block on the same page: “For details, please check the in-game events and announcements.” The calendar is the schedule. The rules are somewhere you cannot read yet.
FAQ
When does Aniimo’s first season of events start?
The first dated event windows open on 16 September 2026, the same day Aniimo launches on PC and consoles. Who’s That Aniimo, Idyll Ecological Investigation, the Journey Handbook and the Trail of Butterfly Shadows all start that day. The calendar gives no time zone, so treat the 16th as a date rather than an hour.
How long does the Aniimo event calendar run?
The Journey Handbook block runs 16 September to 28 October, which is forty-three days, and that block frames almost everything else on the graphic. Two bars run longer: Tracing the Trail and the Irisalis journey both carry a 9 December end date, eighty-one and seventy-six days respectively.
What does UP mean on the Vein Abundance row?
On the graphic it is not an event of its own. Each UP sits inside a named block, after the name, with that creature’s artwork — Prismana Glynsera UP, Prismana Melloblum UP, and so on. It reads as the label on a rate-up window, but the calendar never says what goes up or by how much, and there is no post attached to it that does.
Which Prismana is featured each week?
Glynsera from 21 to 27 September, Melloblum from 28 September to 4 October, Waleetle from 5 to 11 October, Inferlupa from 12 to 18 October, and a Prismana Carnival block from 19 to 25 October. Each runs Monday to Sunday. Before all of them, the Forest of Falling Stars takes 18 to 20 September.
When is Eggceleration active?
Six windows, every one of them Friday to Sunday: 18–20 September, 25–27 September, 2–4 October, 9–11 October, 16–18 October and 23–25 October. Each one lands on the last three days of a Vein Abundance window, which makes the weekend the natural time to hatch what you caught during the week.
Is the Journey Handbook the battle pass?
The calendar does not say so. It lists the Journey Handbook as a name with a date range and nothing else. The paid track confirmed elsewhere is called the Companion Handbook and appears in the Xbox pre-order pack as an in-game battle pass. They may be the same thing under two names, but nothing published connects them.
How long is Aniimo season 1?
The calendar frames it with the Journey Handbook block, 16 September to 28 October — forty-three days. But two bars run past that: Tracing the Trail and the Legendary Journey with Irisalis both carry a 9 December end date. So the farming side of Aniimo season 1 is about six weeks shorter than the story side, and the graphic gives no date at all for what follows December.
Where can I see the calendar myself?
It is on the front page of aniimo.com, under the Event Calendar entry in the site navigation. It is a single image rather than a text page, so it will not show up in a search of the news centre, and the site’s own Event news category is still empty.
