How to Convert Time Zones

Use this time zone converter — also called a timezone converter or time zone calculator — to turn a date and time in one place into local time somewhere else.

  1. Choose where the time starts

    A city, a time zone, or a UTC offset. Eastern Time follows daylight saving; EST stays UTC−5.

  2. Enter the date and time

    Start from the time shown, pick another date, or choose Use current time for the From city or zone.

  3. Choose where it should land

    EST, PST, IST, another city, or another UTC offset — the same way as above.

  4. Read the converted time

    You get local time, any date change, and the time difference. Copy the result 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 ZoneOffset
ESTUTC−5
EDTUTC−4
CSTUTC−6
CDTUTC−5
MSTUTC−7
MDTUTC−6
PSTUTC−8
PDTUTC−7
ISTUTC+5:30
GMTUTC+0

EST is always UTC−5. Eastern Time (ET) switches between EST and EDT with daylight saving time.

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

Daylight Saving Time and Time Zone Conversion

New York and London do not always change clocks on the same weekend. For a few weeks each spring and fall, the usual five-hour gap becomes four or six. That is why a conversion needs a date — not only two zone names.

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.

Time Zone Converter FAQ

What is a time zone converter?
A time zone converter takes a date and time in one city or time zone and shows the matching local time in another. It also shows the UTC offset, whether the date changes, and the time difference between the two clocks.
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 daylight saving time when you select Eastern Time or a city such as New York.
Does the time zone converter account for daylight saving time?
Yes, when you select a city or a zone such as ET, PT, CT, or MT. The date you enter 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.
How do UTC offsets work?
A UTC offset is how far local time sits from Coordinated Universal Time. UTC−5 means five hours behind UTC; UTC+5:30 means five hours thirty minutes ahead. GMT is UTC+0. The gap between two offsets is the time difference between those places.
Can I convert time between cities?
Yes. Search for a city, a label such as EST or PST, or a UTC offset. Cities follow that place’s daylight saving rules for the date you pick, so the conversion stays accurate across seasons.
