Convert CET to EST: The Steady 6-Hour Transatlantic Gap
Central European Time to US Eastern Time is a route used constantly by transatlantic businesses, EU institutions, and anyone calling between cities like Berlin, Paris, or Madrid and New York or Washington. The gap is 6 hours in winter and 5 in summer.
Time Zone Overview
Central European Time (CET)
CET is UTC+1 in winter and CEST (UTC+2) during European DST, which runs from the last Sunday in March to the last Sunday in October.
Eastern Time (EST/EDT)
US Eastern Time is EST (UTC-5) in winter and EDT (UTC-4) during US DST (second Sunday March to first Sunday November).
Time Difference
Winter (both standard): CET is 6 hours ahead of EST.
Summer (both on DST): CET is 6 hours ahead of EDT.
Shoulder weeks: When only the US or only Europe has switched, the gap is 5 or 7 hours for a short stretch.
Conversion Formula
EST = CET − 6 hours (winter) / CET − 6 hours (summer, both DST)
Because both regions observe DST, the 6-hour gap actually holds most of the year — only the few weeks of mismatched switching change it.
