Notes:
1. Server time = UTC+01:00 (Germany, France, Spain, Poland, Italy etc). ~world time zones map~
Bear in mind the above times are in CET (Oct-Mar). In Summer, some of them move +1 hour due to CEST (Mar-Oct) - much like the now-disabled guild BAMs spawn times, but most remain unchanged.
Affected by the +1 hour difference: Log-in time event for Astral Gifts.
Unaffected by the +1 hour difference: TERA Club daily perks, Dungeon daily entries, Guild daily quests, Vanguard daily quests.
If a category isn't mentioned as affected or otherwise, this means I don't enough have information about it.
2. Repeatable quests defined by your item level (up to 16 quests overall per character per day, except the IoD top tier quests).
3. 10 quests for regular players and 20 for Tera Club subscribers; done only by people farming credits for the free black puma mount.
4. If a guild quest gets carried over, i.e. it's still not completed at 7 am, its progress and remaining time will not reset and it will consume a quest slot from the next day's quota when delivered/failed/cancelled.
5. You have to be online, otherwise the reset might not occur.
6. Content removed.
7. If bugged, check Tera EU - Calendar Bug Fix.
7.1. Sometimes you're required to wait 24 hours, sometimes the requirement is to just log in for the day.
7.2. There's usually a 'login requirer' - to complete 1 Vanguard quest before you can collect your freebie. You can 'stock up' on different VG quests, i.e. keep them as completed but undelivered for days you know you won't be able to do more than simply logging in. Don't forget to deliver your quest if you're doing the same activity a second time.
8. An account-wide buff per server - logging into any character counts towards your daily login on that server. Open Calendar (System Menu) to check status. If you were online when the new day started, this would count as having logged in for that day too.
9. The event Star Traces activates at 5 am on Saturday morning, the daily bar resets at 5 am on Sunday morning and both bars disappear at midnight on Sunday.
10. There's a known bug about Humedras in Ex Prima who spawns only once a week (after the weekly server restart).

Have fun!
