This converter translates a date and time between time zones for calls, travel, deadlines, and avoiding the classic one-hour mistake.
The interactive time zone converter loads right here. If it hasn't appeared, refresh the page.
Enter the local date and time, select its time zone, then select the destination time zone. Include the date because the converted time may fall on the previous or next day.
The conversion uses UTC as the reference: UTC time = source local time - source UTC offset, then destination time = UTC time + destination UTC offset. Applicable daylight saving rules determine the offsets for the selected date.
At 3:00 PM on July 15 in Los Angeles, the UTC offset is typically -7 hours, so the UTC time is 10:00 PM. London is typically at +1 hour then, giving a converted time of 11:00 PM on July 15.
Yes, when named time zones and the correct date are used. Fixed UTC offsets do not contain daylight saving rules, so they may be wrong for part of the year.
Time zones can differ enough to cross midnight during conversion. The destination may therefore be on the previous or next calendar day.
