1am Israel is 10:00 pm UTC the previous day
1am IDT is 10:00 pm UTC in Coordinated Universal Time, on the previous day. UTC is 3 hours behind Israel today, and that gap changes during the year, so this is recomputed rather than assumed.
What time is 1am Israel in UTC?
It is 10:00 pm. UTC is 3 hours behind Israel, so you subtract 3 hours from 1:00 am and the result lands on the previous day. 1am is the small hours in Israel, the deadest part of the night, while 10:00 pm is late evening in UTC, the wind-down before midnight.
Spoken as military time, 1am is 0100 hours and the result is 2200 hours. The military convention exists precisely because "3 o'clock" is ambiguous twice over: once on the 12 hour clock and once across zones.
1am Israel to UTC in the hours either side
The four hours before and after 1am, in case the meeting moves. Note that the calendar date does not stay put across this window: it changes partway through, which is exactly where scheduling mistakes come from.

Is 1am Israel a good time to call UTC?
No. 10:00 pm in UTC is late evening, the wind-down before midnight. Nobody is taking that call. The zones are 3 hours apart, so the nearest sensible slot is a different hour entirely.
Does daylight saving change 1am Israel to UTC?
Yes. Sampled at 1am on every day of 2026, the gap takes 2 different values. Today it is 3 hours, which is why the answer above is dated rather than fixed.
Israel Time is currently on IDT and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+3 to UTC+2.
Coordinated Universal Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
1am UTC to Israel, the other way round
Running the question the other way is a different conversion, not a mirror image, because the two zones can be in different daylight saving states on the same date. 1am UTC is 4:00 am Israel, which is a different reading from the answer above, because the two directions are separate questions. One wrinkle worth knowing: IST and IDT are two names for the same zone, not two zones. Israel Time reads IST in winter and IDT in summer. When somebody types "israel to utc" they nearly always mean the zone rather than the literal winter offset, so this page resolves ISRAEL to Asia/Jerusalem and UTC to Etc/UTC and applies whichever offset is genuinely in force on the day.
