- 3. See the local timeGet the converted time, the gap and a world clock table.
Why the date matters
Offsets are not fixed everywhere. India stays at UTC+5:30 all year. New York moves between UTC−4 in summer and UTC−5 in winter. So the gap with India changes during the year.
Here are two worked examples:
- 15 July 2026, 10:00 am IST is 12:30 am the same day in New York. New York is 9.5 hours behind.
- 15 January 2027, 10:00 am IST is 11:30 pm on 14 January in New York. New York is 10.5 hours behind.
This tool uses your browser's time zone data, which follows the rules for each zone, so you do not need to remember them.
Times that happen twice or not at all
Where clocks change, some times are unusual. When clocks jump forward, an hour is skipped. In New York on 8 March 2026, the time 2:30 am does not exist. The tool tells you and uses the closest valid moment.
When clocks go back, an hour repeats. On 1 November 2026, 1:30 am happens twice in New York. The tool uses the earlier one and says so.
Tips for meetings
When you set a meeting, write the date and the time zone with the time. Dates can differ across zones, as the January example shows. For a call between India and the US, check the date again near March and November, since the gap changes then.
Not every offset is a whole hour. India is on a half hour, and Nepal is at UTC+5:45.
For counting days, use the date calculator. For age on a date, use the age calculator.
