Time Zone Converter
Compare any two time zones instantly — correct for Daylight Saving Time on the exact date you pick. No sign-in nudges, no ads.
How this converter works
Instead of using fixed offsets that break twice a year at Daylight Saving Time changes, this tool uses your browser's built-in IANA timezone database — the same one used by Windows, macOS, and Linux — to calculate the real offset for the exact date you choose. That means a conversion in July and the same conversion in January will correctly account for DST in each zone independently.
Common uses
Scheduling a meeting across offices, calling family in another country, planning a flight departure/arrival, coordinating a live stream or webinar audience, or just figuring out what time it is right now somewhere else.
Frequently asked questions
How do I convert a time from one time zone to another?
Pick your "From" time zone and enter the date/time, then pick a "To" time zone — the converted date and time appear instantly. Daylight Saving Time is handled automatically using each zone's real rules, not a fixed offset.
What is EST in PST, or PST in EST?
Eastern Time is normally 3 hours ahead of Pacific Time (so 12:00 PM EST is 9:00 AM PST). Use the "Popular conversions" shortcuts above the tool to load this pair instantly — the exact offset is calculated for your specific date since it can shift by an hour around Daylight Saving Time changes.
Does this tool account for Daylight Saving Time automatically?
Yes. Conversions use each time zone's real, up-to-date DST rules (via your browser's built-in timezone database), so the result is correct for the specific date you enter — not a fixed year-round offset that could be wrong for half the year.
Is this time zone converter free with no signup or app install?
Yes. No account, no email, no app download, and no ads. It runs entirely in your browser and nothing you enter is stored or sent anywhere.
