In short

Istanbul time (UTC+3) is 8 hours ahead of EST (UTC−5) in standard time. 7:10 PM EST is 3:10 AM the next day Istanbul time. During daylight saving time (roughly March to early November) the gap is 7 hours, so 7:10 PM EDT is 2:10 AM the next day Istanbul time.

About EST to Istanbul Time

EST covers New York, Toronto, Atlanta, Miami and Boston. Istanbul covers Istanbul, Ankara and Izmir.

Working days overlap between 09:00 and 11:00 EST, which is 16:00–18:00 in Istanbul. That window is where calls land without anyone working late.

The clocks do not change on the same day, so a recurring meeting can shift by an hour in March and again in November. Check any standing call in the two weeks after each change.

How it works

Turkey Time (Istanbul) is 8 hours ahead of Eastern Time (New York) between November and March, and 7 hours ahead the rest of the year.

  1. Take the EST time you want to convert.
  2. Add 8 hours between autumn and spring, or 7 hours during daylight saving.
  3. Roll the date forward or back if the result crosses midnight.

The gap changes because the two places start and end daylight saving on different dates — for a few weeks each spring and autumn the difference is an hour off its usual value. The converter above uses the live IANA time zone database, so it is right on those days too.

Zone details: EST is −5 in winter and −4 in summer (UTC), Istanbul is +3 all year.
