Paste any numeric Unix timestamp in seconds, milliseconds, microseconds, or nanoseconds, or pick a date/time using the interactive calendar picker.
Read Local Time, UTC/GMT, ISO 8601, RFC 2822, relative time, ISO week number, day of year, and leap year details instantly.
One-click copy formatted date strings or code snippets for JS, Python, Go, Java, PHP, Rust, and SQL, or download bulk conversion CSV files.
Zero network transmission. All date parsing, epoch arithmetic, and timezone conversions occur locally inside browser memory.
Displays live current Unix timestamp in seconds, milliseconds, microseconds, and nanoseconds with instant copy controls.
Intelligently parses input integer timestamps in seconds (10 digits), milliseconds (13 digits), microseconds (16 digits), or nanoseconds (19 digits).
Outputs Local Time, UTC/GMT Time, ISO 8601, RFC 2822, relative time ('in 3 hours', '5 days ago'), day-of-week, day-of-year, week number, and leap year status.
Interactive visual date-time selector supporting UTC, Local Time, EST, PST, CET, IST, JST, and custom UTC offsets.
Bulk convert multiple lines of timestamps to dates (or vice versa) with downloadable CSV/JSON export, plus ready-to-copy code snippets for JS/TS, Python, Go, Java, PHP, Rust, and SQL.
Our Unix Timestamp Converter & Date Formatter engine is open source under HiMat Technology. Star the repository, inspect the source, report issues, or contribute on GitHub.
Third-party epoch converters often log database queries and internal system logs on remote servers. HiMat's Timestamp Converter operates entirely inside your web browser using client-side JavaScript APIs. Zero data is transmitted over the network.
A Unix timestamp (or Epoch time) represents the total number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch), excluding leap seconds. It is widely used in computing databases, APIs, and logging systems.
No. The HiMat Unix Timestamp Converter operates 100% locally inside your web browser using JavaScript Date and Intl Web APIs. Zero network calls leave your local machine.
Our auto-detection engine analyzes integer length: 10 digits indicate seconds (e.g. 1700000000), 13 digits indicate milliseconds, 16 digits indicate microseconds, and 19 digits indicate nanoseconds.
32-bit signed integers overflow on January 19, 2038. Because modern modern web browsers use 64-bit IEEE 754 floating point numbers and BigInts, our tool seamlessly handles dates past 2038 up to year 275,760.
