AoE is UTC−12. Central European Time (CET and CEST) is UTC+1 in winter and UTC+2 in summer, so it is 13 hours (winter) or 14 hours (summer) ahead of AoE. 23:59 AoE is 12:59 CET in winter and 13:59 CEST in summer, on the next day.
The common deadline times, worked out for Central European Time (CET and CEST). Both columns are shown because the answer depends on whether the deadline date falls in winter or summer.
| AoE time | Winter (CET) | Summer (CEST) |
|---|---|---|
| Midnight (00:00, 12:00 AM) | 13:00 CET | 14:00 CEST |
| 06:00 (6:00 AM) | 19:00 CET | 20:00 CEST |
| 12:00 (noon) | 01:00 CET (next day) | 02:00 CEST (next day) |
| 17:00 (5:00 PM) | 06:00 CET (next day) | 07:00 CEST (next day) |
| End of day (23:59, 11:59 PM) | 12:59 CET (next day) | 13:59 CEST (next day) |
Most of continental Europe changes its clocks on the same weekends, so a deadline in summer is on CEST even if it is written CET.
Central European Time is CET (UTC+1) from the last Sunday in October to the last Sunday in March and CEST (UTC+2) the rest of the year.
12:59 CET (UTC+1) in winter, and 13:59 CEST (UTC+2) in summer, on the next day. Use the deadline's own date to pick the right one.
13:00 CET in winter and 14:00 CEST in summer, on the same day. Midnight AoE is the start of the deadline date, so it is the earliest the date can begin anywhere.
In winter, CET is 13 hours ahead of AoE; in summer, CEST is 14 hours ahead. AoE itself never changes: it is UTC−12 all year.
Yes, because European clocks change and AoE does not. Central European Time is CET (UTC+1) from the last Sunday in October to the last Sunday in March and CEST (UTC+2) the rest of the year.
AoE means Anywhere on Earth. The deadline passes only when the stated date has ended in every time zone, which happens last in UTC−12. If it is still the deadline date anywhere on Earth, you are on time.
