CONVERTER
Date to Unix timestamp
Convert a human date to a Unix timestamp in epoch seconds or milliseconds. Free two-way converter for APIs, JWTs, and databases.
Enter a date and get its Unix timestamp — the single UTC number APIs, JWT exp claims, and databases prefer. Choose seconds or milliseconds to match your target.
Pick the right unit
Classic Unix time is seconds; JavaScript and many web APIs use milliseconds. Decide which your destination expects and stay consistent — mixing units is the most common timestamp bug.
Mind the timezone
A timestamp is UTC. Enter the date in UTC (or account for your offset) so the resulting number points at the moment you actually mean.
