Convert EST to CET
To convert EST to CET: 9:00 AM EST is 3:00 PM CET. EST is UTC-05:00 and CET is UTC+01:00, so CET is 6 hours ahead of EST, but not all year, as explained below.
In Central European Time
- On a 24-hour clock
- 09:00 EST is 15:00 CET
- The offsets
- EST is UTC-05:00, CET is UTC+01:00
- Difference
- CET is 6 hours ahead of EST
- Date
- Same calendar day.
- This gap does NOT hold all year Convert through the offset in force on the date you care about.
- The two ends switch on different dates, or one does not switch at all.
- EST is only in force part of the year United States: daylight time starts the second Sunday in March, at 02:00 local time and ends the first Sunday in November, at 02:00 local time (Energy Policy Act of 2005, in force since 2007). In 2026 that is 2026-03-08 to 2026-11-01. New York is on EDT between those dates.
- otherwise EDT, UTC-04:00
- Military time zone letters Z (Zulu) is UTC. A to M run east of Greenwich an hour apart, N to Y west, and J is left out. A letter names an offset, so a zone that switches to daylight time changes letter: EST is R, EDT is Q.
- EST is R (Romeo), CET is A (Alfa)
- In every zone

How the Time Zone Converter works
Eastern Standard Time (EST) is UTC-05:00 and Central European Time (CET) is UTC+01:00, so converting EST to CET means adding 6 hours to the EST time. CET is 6 hours ahead of EST.
Worked through: 9:00 AM EST is 3:00 PM CET.
The gap between these two is not the same all year, which is the thing to get right. the two zones switch on different dates (EST under the United States rule and CET under the European Union and United Kingdom one), so the difference moves. Convert through the offset in force on the date you care about rather than through the abbreviation somebody typed; the offsets above are definitions and the abbreviation is a claim about the calendar.
Six hours forward, the standard transatlantic business gap, and the one the three-week March window distorts. Europe switches on the last Sunday in March and the US on the second, so between those dates New York is on EDT and Paris is still on CET, making the gap five hours instead of six. A recurring 10:00 New York call that is 16:00 in Paris for most of the year is 15:00 in Paris for three weeks in March, and the calendar software usually gets this right while the humans reading the invitation do not.
One thing worth stating plainly, because it is the most common mistake in this whole subject: an abbreviation is not a place. EST is Eastern Standard Time, which New York uses only part of the year; the rest of the time it is on EDT at UTC-04:00. CET is likewise only in force for part of the year in Paris; otherwise it is CEST at UTC+02:00. If what you have is a city and a date rather than a pair of abbreviations, that is a different question and needs the tz database, not arithmetic. This is also why the shifting designations exist: ET means Eastern time whichever of the two is in force. Searching for ET and searching for EST to CET are the same question in two vocabularies, which is why this converter answers both.
Common times for this pair:
- 8:00 AM EST is 2:00 PM CET - 9:00 AM EST is 3:00 PM CET - 10:00 AM EST is 4:00 PM CET - 12:00 PM EST is 6:00 PM CET
Time Zone Converter FAQ
What is the time difference between EST and CET?
CET is 6 hours ahead of EST. EST is UTC-05:00 and CET is UTC+01:00, and both offsets are definitions rather than measurements, so the subtraction is exact.
What time is 9:00 AM EST in CET?
9:00 AM EST is 3:00 PM CET. Add 6 hours and carry the date if it crosses midnight.
Does the difference between EST and CET change with daylight saving?
Yes, and this is the main thing to watch on this pair. the two switch under different rules and on different dates, so the difference takes more than one value across the year. In 2026 the United States switch runs from 2026-03-08 to 2026-11-01.
Is there anything specific to this pair worth knowing?
Six hours forward, the standard transatlantic business gap, and the one the three-week March window distorts. Europe switches on the last Sunday in March and the US on the second, so between those dates New York is on EDT and Paris is still on CET, making the gap five hours instead of six. A recurring 10:00 New York call that is 16:00 in Paris for most of the year is 15:00 in Paris for three weeks in March, and the calendar software usually gets this right while the humans reading the invitation do not.
Someone wrote EST but it is summer. What do they mean?
Almost certainly the zone rather than the abbreviation: New York time, which in summer is EDT at UTC-04:00 rather than EST at UTC-05:00. People type the standard-time abbreviation all year round. If an invitation is an hour out from what you calculated, this is why.
