21:00 CET to EST

15:00 EST

21:00 Central European Time equals 15:00 Eastern Standard Time.

These are standard-time offsets, which never change. What changes is which one a place observes: New York is on EST in winter but EDT (an hour later) during daylight saving, and the UK is on GMT in winter and BST in summer. If you mean "the time in New York right now", use the full converter — it reads live offsets.

How the conversion works

This one is a formula rather than a single multiplier:

EST = CET − 6 hours → 15:00 EST

Going the other way: 15:00 EST to CET.
