What are the best hours to schedule a call between AEST and WEST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. Australian Eastern and Lisbon are 9 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| AEST | WEST | Working hours | Note |
|---|---|---|---|
| 4:00 pm | 7:00 am | AEST only | afternoon in Australian Eastern, early morning in Lisbon |
| 5:00 pm | 8:00 am | neither side | evening in Australian Eastern, mid morning in Lisbon |

Does daylight saving change AEST to WEST?
Australian Eastern Time is currently on AEST and changes next on Sunday, October 4, 2026, when the clock jumps forward from 1:59 am to 3:00 am and the offset moves from UTC+10 to UTC+11.
Western European Time is currently on WEST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Because the two sides do not move together, the answer to this conversion changes during the year. The United States changes on the second Sunday in March and the first Sunday in November, while the United Kingdom and European Union change on the last Sunday in March and the last Sunday in October. Those dates are weeks apart, which opens a window each spring and autumn where the usual gap is an hour out. The table above is built for today, not for an average day.
Is AEST ahead of or behind WEST?
AEST is ahead of WEST by 9 hours: when it is 12:00 pm in Australian Eastern, it is 3:00 am in Lisbon. One wrinkle worth knowing: AEST and AEDT are two names for the same zone, not two zones. Australian Eastern Time reads AEST in winter and AEDT in summer. When somebody types "aest to wet" they nearly always mean the zone rather than the literal winter offset, so this page resolves AEST to Australia/Sydney and WET to Europe/Lisbon and applies whichever offset is genuinely in force on the day.
Australian Eastern Time covers Sydney, Melbourne and Canberra, where summer falls in December. Western European Time covers Lisbon, Porto and the Canary Islands, one hour behind most of the continent. The identifiers behind them are Australia/Sydney and Europe/Lisbon, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
