- EDT is Eastern Daylight Time, UTC-4.
- Use a city plus date, such as New York on July 26, for exact conversion.
Why this matters
If someone says EST during summer, they may actually mean Eastern Time in New York, which is EDT. This can shift meetings by one hour.
Best practice
Use city names and dates instead of abbreviation-only input. New York to Mumbai on a date is safer than EST to IST without context.
