What time zones are supported?

30+ time zones including UTC, GMT, EST (New York), CST (Chicago), PST (Los Angeles), CET (Paris), MSK (Moscow), IST (Mumbai), CST (Beijing), JST (Tokyo), SGT (Singapore), AEST (Sydney), NZST (Auckland), and more. Each zone shows the major city it represents.

How does Daylight Saving Time work?

Toggle the DST option to apply daylight saving time adjustments. Not all time zones use DST. For example, EST becomes EDT (UTC-4) during DST, while JST (Japan) does not observe DST. The tool automatically shows the correct offset when DST is enabled.

What does '+1 day' or '-1 day' mean?

When the converted time crosses midnight, the tool shows the day difference. '+1 day' means the result is on the next day, '-1 day' means the previous day. This is essential for scheduling meetings that span multiple days.

Should I use 12-hour or 24-hour format?

Use 24-hour format (14:00) for international business and military contexts. Use 12-hour format (2:00 PM) for casual use or when communicating with people in regions that prefer it (like the US). Both formats are supported.
