Convert between Unix timestamps and human-readable dates with timezone support
A Unix timestamp converter is a tool that converts between Unix time (also called epoch time) and human-readable date formats such as ISO 8601, local date strings, and timezone-adjusted time values. Unix timestamps represent the number of seconds (or milliseconds) since January 1, 1970 at 00:00:00 UTC, and are widely used in programming, APIs, databases, system logs, and distributed systems because they provide a consistent and timezone-independent way to represent time. This online Unix timestamp converter helps you instantly decode timestamps into readable dates, convert dates back into timestamps, and view results across different timezones. It is essential for debugging logs, verifying event timing, inspecting API payloads, and preventing timezone-related bugs.
Paste a Unix timestamp (seconds or milliseconds) into the input field
Or paste a date/time value such as an ISO 8601 string or natural language date
