Date & Time
Unix Timestamp Converter
Loading the tool…
Turn a Unix timestamp into a readable date in one or two time zones, with the time difference, or pick a date and get its timestamp.
How to use this tool
To convert a Unix timestamp, enter the value and select or auto-detect its unit. To go the other way, enter a date and time under Date to timestamp.
Choose a Time zone, and a second place under Compare with, to see every date in both places and how far apart they are. Use the swap button to reverse them.
Copy the date, seconds, or milliseconds you need, or choose Use current time to start again from now.

Epoch time without the guesswork.
A Unix timestamp counts the seconds since 1 January 1970 UTC. It is how logs, databases, and APIs record time, and it is unreadable until converted.
- Any unit
- Seconds, milliseconds, microseconds, and nanoseconds are told apart by size, or you can choose the unit yourself when it is ambiguous.
- Two time zones at once
- Pick a second place to see the same moment in both, such as the Philippines and Tokyo or the US and Australia, with the time difference between them. Daylight saving is applied for that exact date.
- Both directions
- Pick a date and time to get the timestamp in seconds and milliseconds, read in whichever zone you choose.
Frequently asked questions
How do I know if a timestamp is in seconds or milliseconds?
Count the digits. A timestamp for a date in the last few decades has 10 digits in seconds and 13 in milliseconds. The converter uses that to guess, and you can override it.
How do I compare two time zones?
Choose one place under Time zone and another under Compare with. Every date on the page is then shown in both, and the difference between them, such as Tokyo being 1 hour ahead of Manila, is worked out for that exact moment. The swap button trades the two places.
How do I choose a time zone?
Use the two quick choices, Your device and UTC, or search: type a country (philippines), a city (manila), an abbreviation (EST, PHT, CET) or an offset (UTC+8). A country with several zones, such as the United States, lists each one. An offset like UTC+8 is fixed all year, while a city follows its own daylight saving.
Why is my date off by some hours?
A timestamp is a single instant, but the clock time you see depends on the time zone. Check the time zone field: UTC and your local time differ by your offset.
What is the year 2038 problem?
Systems that store seconds in a signed 32-bit number run out on 19 January 2038. This tool uses 64-bit arithmetic, so it converts dates far beyond that.
Does it handle daylight saving time?
Yes. When converting a date to a timestamp, the zone's offset for that specific date is used, so a time in July and a time in January are treated correctly.
