A time zone converter translates a time from one world time zone to another in
a single step. Select the source and target zones from 30+ options — including
UTC, EST, PST, IST, CET, JST, AEST and many more — enter the time in 24-hour
format, and see the result instantly.
The calculator handles half-hour and quarter-hour offsets (like India’s UTC+5:30
and Nepal’s UTC+5:45) and shows a “+1 day” or “−1 day” indicator when the
conversion crosses midnight. It also displays the total time difference between
the two zones in hours.
This is ideal for scheduling international calls, planning travel, coordinating
remote teams, and converting meeting times across regions.

Frequently asked questions
How do I convert between time zones?
Select the source and target time zones, enter the time you want to convert, and the calculator instantly shows the equivalent time in the target zone.
Does it account for daylight saving time?
This calculator uses fixed UTC offsets. For precise DST-adjusted times, note that many regions shift by 1 hour during summer months.
What is UTC?
UTC (Coordinated Universal Time) is the primary time standard. Time zones are defined as offsets from UTC, for example EST is UTC-5 and IST (India) is UTC+5:30.
How do I know if it is the next day?
If the converted time goes past midnight, the result shows a +1 day indicator. If it goes before midnight backwards, it shows a -1 day indicator.
What is the time difference between EST and IST?
EST (UTC-5) to IST (UTC+5:30) is a 10.5-hour difference. When it is 9:00 AM EST, it is 7:30 PM IST.
