Time difference between Istanbul and Rome

Rome is 1 hour behind Istanbul

Istanbul, Türkiye is UTC+3 · 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 Istanbul does not change its clocks and Rome goes forward on the last Sunday in March and back on the last Sunday in October.
