Roughly 60 per cent of the world’s population never adjusts a clock. If your team spans a DST country and a non-DST country, the offset between you changes twice a year even though neither of you did anything.
The mismatch weeks
14 MAR – 28 MAR
North America on summer time, Europe not: the Atlantic gap narrows by an hour for these weeks, so a recurring call lands an hour early for one side.
31 OCT – 7 NOV
Europe back on winter time, North America not: Berlin is five hours ahead of New York rather than six until the United States follows.
3 APR – 2 OCT
Australia on winter time while Europe is on summer time: the gap swings by two hours across the northern summer.
