Quick answer
To convert a Unix timestamp to a date, paste it into the "Timestamp → date" box of the KaviForge Unix Timestamp Converter. It auto-detects whether the value is in seconds (10 digits), milliseconds (13 digits), microseconds, or nanoseconds, and shows the date in UTC, your local time zone, ISO 8601, and relative time. Use "Date → timestamp" for the reverse.
A Unix timestamp (epoch time) is the number of seconds since 00:00:00 UTC on 1 January 1970. It is how databases, APIs, logs, and JWTs store time because it is time-zone independent and easy to compare.
JavaScript and many APIs use milliseconds instead of seconds, which is a common source of bugs. This converter detects the unit automatically so you always get the right date.
How to Convert a Unix Timestamp
- 1The current Unix time is shown at the top, updating every second — copy it with one click.
- 2Paste a timestamp into "Timestamp → date"; the unit is detected automatically.
- 3Read the date in UTC, local time, ISO 8601, and relative form.
- 4To go the other way, pick a date and time in "Date → timestamp".
- 5Choose whether that date is in your local time zone or UTC, then copy the seconds or milliseconds.

When to Use the Unix Timestamp Converter
Debug API and database values
Turn created_at or updated_at integers into readable dates.
Read log timestamps
Convert epoch values in server, Kafka, or CloudWatch logs.
Check token expiry
Convert exp and iat claims from JWTs and OAuth tokens.
Schedule and test time-based code
Generate exact timestamps for cron jobs, cache expiry, or test fixtures.
About the Unix Timestamp Converter
Unit detection is based on the number of digits: up to 11 digits is treated as seconds, 12–14 as milliseconds, 15–17 as microseconds, and more as nanoseconds. You can override it with the unit selector.
All conversions use your browser’s Date and Intl APIs, so local times respect your time zone and daylight saving rules.
Unix Timestamp Converter FAQs
How do I convert a Unix timestamp to a date?
Paste it into the "Timestamp → date" field of the KaviForge Unix Timestamp Converter. The UTC, local, and ISO 8601 dates appear instantly.
What is the current Unix timestamp?
It is shown live at the top of the tool in seconds and milliseconds. Click "Copy seconds" to copy it.
Is my timestamp in seconds or milliseconds?
A 10-digit value is usually seconds and a 13-digit value is milliseconds. The converter detects this automatically.
How do I convert a date to a Unix timestamp?
Use the "Date → timestamp" section: pick the date and time, choose Local or UTC, and copy the Unix seconds or milliseconds.
Are Unix timestamps affected by time zones?
No. A Unix timestamp always counts seconds from 1970-01-01 in UTC. Only its display as a date depends on time zone.
What is the year 2038 problem?
Systems that store Unix time as a signed 32-bit integer overflow on 19 January 2038. Modern 64-bit systems and JavaScript are not affected.
