Time difference between Tokyo and Rome

Rome is 7 hours behind Tokyo

Tokyo, Japan is UTC+9 · Rome, Italy is UTC+1 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Tokyo does not change its clocks and Rome goes forward on the last Sunday in March and back on the last Sunday in October.

Tokyo stays put all year while Rome moves, so the gap changes twice a year from Rome's side alone. A recurring meeting set in Tokyo's calendar will drift by an hour without anyone touching it.
