How do I convert time between time zones?

Choose the source city or time zone, enter a date and time, then choose the destination. The converter shows the same moment on both clocks, including any date change when the result crosses midnight.

Does this converter account for daylight saving time?

Yes, when you select a city or a zone such as ET, PT, CT, or MT. The date decides whether that place is on standard time or daylight saving time. If you select EST or PST, that clock does not change with the season.

What is the difference between EST and ET?

EST is Eastern Standard Time, always UTC−5. ET is Eastern Time for New York and the US East Coast. ET is EST in winter and EDT (UTC−4) during daylight saving time. The same distinction applies to PT vs PST, CT vs CST, and MT vs MST.

Is PST the same as Pacific Time?

No. PST is Pacific Standard Time, always UTC−8. Pacific Time (PT) switches between PST and PDT (UTC−7) with the date. Choose PST when you want UTC−8 every day of the year; choose PT or a West Coast city when you need local time for that day.

Why does the time difference change during the year?

Two places can start or end daylight saving time on different weekends. New York and London are usually five hours apart, but for short stretches when only one side has changed clocks, London is four hours ahead of New York. Always convert with a date, not only two zone names.

What happens if a time occurs twice during DST?

When clocks fall back, some local times happen twice — once in daylight time and once in standard time. The converter marks the overlap and lets you pick the first or second clock so you convert the moment you mean.

Can I convert a meeting time to another calendar day?

Yes. Long gaps such as PST to IST often land on the previous or next day. The result shows the destination local time and whether the date changes, so you can schedule across midnight with confidence.

How to Convert Time Zones

Same idea as a simple time zone calculator: one moment on two clocks. Work through the steps below to convert time zones for any date.

Choose the source time zone
A city, Eastern Time or Pacific Time, a label such as EST, or a UTC offset.
Enter the date and time
Pick any date, or use current time for the From city or zone.
Choose the destination time zone
EST, PST, IST, another city, or another UTC offset.
View the converted time
Local time, any date change, and the time difference — copy when you need it.

Understanding Time Zones and UTC Offsets

A UTC offset is how far local time sits from Coordinated Universal Time. GMT is UTC+0. IST is UTC+5:30 all year.

Time Zone	Offset
EST	UTC−5
EDT	UTC−4
CST	UTC−6
CDT	UTC−5
MST	UTC−7
MDT	UTC−6
PST	UTC−8
PDT	UTC−7
IST	UTC+5:30
GMT	UTC+0

EST is always UTC−5. Eastern Time (ET) switches between EST and EDT with daylight saving time. PST is always UTC−8; Pacific Time (PT) switches between PST and PDT.

The same split holds for Central and Mountain time: CT is not CST, and MT is not MST. Choose EST, EDT, PST, or PDT when you need that exact clock. Choose Eastern Time, Pacific Time, or the city when you need local time for the date you enter.

Daylight Saving Time and Time Zone Conversion

New York and London are usually five hours apart. For a few weeks each year, the U.S. and U.K. change clocks on different weekends, and London is only four hours ahead of New York. Use the exact date to get the correct time difference.

Eastern Time uses EST in standard time and EDT during daylight saving time. Pacific Time uses PST, then PDT. Pick Eastern Time or New York and the date chooses EST or EDT. Pick EST and you keep UTC−5 even in July — the converter will not switch you to EDT.

India Standard Time and UTC never observe DST. The United Kingdom does, so GMT and London are not the same clock in summer. For a meeting months away, set the date first, then the cities.

What Happens When Clocks Change?

When daylight saving time starts, some local times do not exist. When it ends, some local times happen twice. The converter flags those cases and lets you choose the first or second clock when a time repeats.

Example 1 — A time that does not exist

Mar 8, 2026 · 2:30 AM

New York local time

Skipped time

Clocks jump from 2:00 AM to 3:00 AM. If you enter 2:30 AM, the converter moves ahead to the next real local time: 3:30 AM EDT.

Example 2 — A time that occurs twice

Nov 1, 2026 · 1:30 AM

New York · when clocks fall back

Which time	Local	UTC
First	1:30 AM EDT	05:30 UTC
Second	1:30 AM EST	06:30 UTC

Enter the exact date, then pick the first or second clock when a time repeats. For a related US–UK pair page, see EST to GMT (fixed labels), or go back to the time zone converter for cities and dates.
