18:25 at UTC+3.00 converts to 15:25 at UTC+0.00 (same calendar day).

Formula

How it is calculated

target = source time โˆ’ source UTC offset + target UTC offset
  1. Enter the source clock time.
  2. Remove its explicit UTC offset.
  3. Add the target UTC offset and note any date shift.

What the result means

This converts fixed offsets only. It does not identify a time zone or infer daylight-saving rules for a date.

All decision-bearing times, offsets or coordinates remain visible inputs. The page does not look up a hidden local convention, mosque timetable or current location.

Limits and local confirmation

UTC offsets can change with daylight-saving or government rules. Confirm the applicable offsets for both locations and date.

For worship planning, confirm the applicable times, method and interpretation with the local mosque or authority you follow.

Questions about this calculation

Does this time-zone calculator choose prayer times for me?

No. It uses only the timetable values or coordinates you enter. Obtain prayer times and method guidance from a trusted local timetable, mosque or authority.

Does it store my values or location?

No. The arithmetic runs in your browser and the form does not submit coordinates, times or results to a server.

What happens when an interval crosses midnight?

Clock-interval tools move forward on a 24-hour clock, so an end time earlier than the start is treated as occurring on the following calendar day.
