Understanding the Paris – Boston Time Difference
Paris runs on Europe/Paris, currently CEST (UTC+2:00). Boston runs on America/New_York, currently EDT (UTC-4:00). The gap of 6 hours is simply the distance between those two offsets.
Both cities observe Daylight Saving Time, but they don't switch on the same date — so for a few weeks each year the gap between them is different again. The next shift is on Sunday, October 25, 2026, when Paris adjusts its clocks and the difference becomes 5 hours. Anything scheduled across that date needs checking again.
