Every dated window in Aion 2 Global starts and ends on the same weekly boundary: Wednesday at 07:00 UTC, which the game writes as 16:00 on its UTC+9 clock. The season calendar puts every window the game defines on one month timeline in your own time zone, with each Daeva Pass reward track level by level and a calendar file for each window.
Seasons
The game defines four seasons: 
Season 1 lasts 11 weeks, the others 12.
| Season | Starts | Ends | Season Rewards until |
|---|---|---|---|
| Season 1 | 30 Sep 2026 | 16 Dec 2026 | 10 Mar 2027 |
| Season 2 | 16 Dec 2026 | 10 Mar 2027 | 2 Jun 2027 |
| Season 3 | 10 Mar 2027 | 2 Jun 2027 | 25 Aug 2027 |
| Season 4 | 2 Jun 2027 | 25 Aug 2027 | 17 Nov 2027 |
Each season runs 
Nightmare, 
Transcendence, the 
Abyss, the 
Arena and the 
Ascension Trial, and Seasons 2 and 3 add 
Subjugation. Its Season Rewards window opens when the season ends and stays open through the whole of the next season. The Transcendence dungeons the season features change: 
Deus Research Base and 
Shattered Arkanis in Seasons 1 and 4, joined by 
Submerged Life Temple in Season 2 and by Submerged Life Temple and Mirror of Scarlet Desire in Season 3.
The Arena of Tactics keeps its own season windows. The two the game has dated match Seasons 1 and 2 exactly.
Daeva Pass
A Daeva Pass runs with each of the first two seasons, and an event pass runs for the first four weeks of Season 1:
| Pass | Runs | Levels | EXP to the last level | Weekly EXP limit | Premium |
|---|---|---|---|---|---|
| Dawn Legion / Ishalgen Mercenary | 30 Sep to 16 Dec 2026 | 101 | 199,400 | 50,000 | 1,500 Quna |
| Planet's Call | 30 Sep to 28 Oct 2026 | 51 | 40,000 | 15,000 | 1,000 Quna |
| New Tide | 16 Dec 2026 to 10 Mar 2027 | 101 | 199,400 | 50,000 | 1,500 Quna |
The Season 1 pass is Dawn Legion for Elyos and Ishalgen Mercenary for Asmodians, with the same rewards at every level. Levels 1 to 12 cost 1,500 pass EXP each. The cost then rises by 100 at a time, each step a little sooner than the last, to 2,500 for levels 95 to 100, and level 101 costs 5,000.
The weekly limit sets the fastest pace on earned EXP. A Daeva Pass needs at least four capped weeks to reach level 101, so a character that starts earning in the last three weeks of the season cannot reach it without buying levels. The event pass needs three of its four weeks.
Premium adds a second reward at every level and an unlock reward: 5 Resurrection Spiritstones for a Daeva Pass, 20 Battle Enhance Scrolls for the event pass. Across all 101 levels the Season 1 Basic track gives 100,000 Kina, 48,000 Enhance Stones and 32 Unique Amplify Stone Fragments; Premium gives 1,000,000 Kina, 120,000 Enhance Stones, 96 Amplify Stone Fragments and 45,000 Daeva Pass Shop Coins. The Fragments arrive in blocks of 12 every ten levels from level 23 to 93 on the Premium track. Season 2 pays its coins as 
Daeva Pass Shop Coin: Season 2, a separate currency.
The coins are spent in the 
Pass Shop (Elyos) or the Asmodian Pass Shop, which sell until 16 December 2026, the same day the Season 1 pass and the 
Season Shop close.
Attendance
Two attendance sheets run from 30 September to 16 December 2026, one check-in per day after the daily reset:
- Launch Celebration Shugo Check-In, 7 days: Kina, Soul Crystals, Centuryroot Tokens, Phantasmal Fragments,
Abyss Points, and 1,000,000 Kina on day 7. - Daily Attendance, 14 days: a seven-day set given twice, from Life Crystals on day 1 to
Odyle Energy on days 7 and 14.
Both sheets give the same rewards to both factions.
Ascension Trial weeks
The Ascension Trial opens one dungeon a week. In Season 1 it alternates Sanctum of Loathing and Nightmare Altar, starting with Sanctum of Loathing on 30 September. From 16 December it alternates Depository of Fates and Tyrant's Hideout. The game dates these weeks up to 20 January 2027; the calendar shows later weeks once the game adds them.
What the game has not dated yet
The game holds no Daeva Pass, attendance sheet or shop sale for Seasons 3 and 4, and no Arena of Tactics window after 10 March 2027. The calendar lists only what the game dates and adds new windows when the game does.
