🌍 TimezoneConverter

Daylight Saving Time (DST) is a system of setting clocks forward by one hour during summer to make better use of daylight. The converter automatically detects and marks whether DST is currently in effect.

You can validate against authoritative sites like timeanddate.com. This tool uses the browser's native Intl API, consistent with the OS timezone database.

You can change the date field to convert past or future dates. Note that DST determination is based on current rules — historical rules may differ.
