These examples always use WT (UTC+0) and EST (UTC-5). They stay the same when you change the date or time above. The selected conversion may differ when daylight saving time applies.

WT is 5 hours ahead of EST.

EST is US Eastern winter time (early November to mid-March). The rest of the year New York uses EDT (UTC-4), one hour later. For Eastern Time that follows daylight saving time, use WT to ET. For daylight-time examples, use WST to EDT.

How the time difference changes

During 2026, the difference changes: WST is 5 hours ahead of EDT, WT is 5 hours ahead of EST, WT is 4 hours ahead of EDT, and WST is 6 hours ahead of EST.

During 2026, working-hour overlap changes: working hours of 9:00 am to 5:00 pm in WST correspond to 4:00 am to 12:00 pm in EDT, working hours of 9:00 am to 5:00 pm in WT correspond to 4:00 am to 12:00 pm in EST, working hours of 9:00 am to 5:00 pm in WT correspond to 5:00 am to 1:00 pm in EDT, and working hours of 9:00 am to 5:00 pm in WST correspond to 3:00 am to 11:00 am in EST.During 2026, working-hour overlap changes: working hours of 09:00 to 17:00 in WST correspond to 04:00 to 12:00 in EDT, working hours of 09:00 to 17:00 in WT correspond to 04:00 to 12:00 in EST, working hours of 09:00 to 17:00 in WT correspond to 05:00 to 13:00 in EDT, and working hours of 09:00 to 17:00 in WST correspond to 03:00 to 11:00 in EST.

Compare WT time with EST time, including current local time, UTC offsets, time difference, daylight saving changes, working hours, and shareable meeting times.

Western Sahara Standard Time

Offset: WT is the same as Greenwich Mean Time (GMT).

Greenwich Mean Time (GMT) originally referred to the mean solar time at the Royal Observatory in Greenwich, London. It is now often used to refer to Coordinated Universal Time (UTC) when this is viewed as a time zone, and in casual use the two are the same. In the military, GMT is known as Zulu time. Greenwich Mean Time was the same as Universal Time (UT), a standard astronomical concept used in many technical fields, until the introduction of UTC in 1972.
