EDT — Eastern Daylight Time
EDT is Eastern Daylight Time, -04:00, used in North America. In code, use America/New_York rather than the abbreviation.
Use the IANA name, not the abbreviation
Python
from datetime import datetime
from zoneinfo import ZoneInfo
# right: an IANA zone carries the full history of rule changes
now = datetime.now(ZoneInfo("America/New_York"))
print(now.isoformat(), now.tzname())
# wrong: an abbreviation is not resolvable, and a hard-coded offset
# silently rots the next time the rules change
# now = datetime.now(timezone(timedelta(hours=...))) # don'tEDT questions
What does EDT stand for?
EDT is Eastern Daylight Time, -04:00, used in North America. The IANA zone to use in code is America/New_York.
What time is it in EDT right now?
Eastern Daylight Time: 20:15 on Wednesday (EDT).
Which IANA timezone should I use instead of EDT?
America/New_York for Eastern Daylight Time. Date libraries cannot resolve bare abbreviations, and an abbreviation carries no daylight-saving history, so a stored offset silently rots when a government changes the rules.
