## About Timezone Conversion

Timezone conversion is essential for coordinating across global teams and scheduling international meetings. Choose a source location and date, then compare the local time in your selected destinations. The browser's time-zone data determines the offset for that date.

### How to Convert a Time Between Zones

1. Enter the date and local time you want to convert.
2. Select the source time zone and one or more destination time zones.
3. Choose a display format and select Convert, then check each result's date and UTC offset.

For example, 12:00 UTC on January 15, 2025 is 17:30 in Kolkata on the same date. For a Unix time instead, use the [Unix Timestamp Converter](https://www.toolcomb.com/unix-timestamp-converter). To convert a duration rather than a clock time, use the [Time Converter](https://www.toolcomb.com/time-converter).

### Understanding UTC Offsets

#### UTC+X Format

Positive offset means ahead of UTC. UTC+5:30 is 5.5 hours ahead of UTC.

#### UTC-X Format

Negative offset means behind UTC. UTC-8 is 8 hours behind UTC.

#### Clock Changes

A local time can be skipped or repeated during a clock change. This tool asks you to choose another time in those cases.

#### Meeting Scheduling

Use multiple timezones to find optimal meeting times for global teams.

### Frequently Asked Questions

#### What is DST?

Daylight Saving Time (DST) is when clocks are moved forward/backward to make better use of daylight.

#### How many timezones are there?

This tool offers a selected list of time zones. Named zones follow regional rules that can change over time.

#### Does this handle DST automatically?

The conversion uses the browser's time-zone rules for the selected date. If a source time is skipped or repeated during a clock change, choose a different time.

#### Can I schedule meetings across timezones?

Yes. Select multiple time zones to compare their local times; the tool does not create a calendar event.
