About this tool
Unix timestamps count seconds (or milliseconds) since 1970-01-01 UTC. APIs, logs, and databases love them; humans don't. This converter runs entirely in your browser — paste a value from a webhook payload, server log, or SQL row and get readable dates back.
Values at or above 1e12 are treated as milliseconds — a common mistake when copying Date.now() output into a seconds-only field. The reverse mode lets you pick a local date and get the epoch back for test fixtures. Timezone output uses your browser's IANA list; it does not call a server.
