How it works
Converts Unix timestamps to local dates and times, and converts calendar dates back to Unix seconds or milliseconds.
Who it's for: Developers debugging logs, JWT exp claims, webhooks, and database epoch columns
Accepts seconds (10 digits) and automatically detects milliseconds (13 digits).
Supports bidirectional conversion: timestamp to date and date to timestamp.
Shows the current Unix timestamp for quick reference.
How to use
- Choose Timestamp → Date or Date → Timestamp mode.
- Enter a Unix value or pick/enter a calendar date and time.
- Read the converted result displayed below the input.
- Use the current timestamp shown on the page when you need “now” in epoch form.
- Copy values into log queries, SQL filters, or API parameters.
Good to know
- Unix time is UTC-based; your browser displays results in your local timezone.
- JavaScript Date uses milliseconds—multiply seconds by 1000 when passing to new Date() in code.
