Convert between Unix epoch timestamps (seconds/milliseconds) and human-readable UTC and local time.
The Todoal Unix Timestamp Converter is an essential developer tool engineered to convert POSIX epoch timestamps into human-readable calendar dates and UTC strings. The Unix timestamp system counts the number of seconds that have elapsed since midnight Coordinated Universal Time (UTC) on January 1, 1970. It serves as the standard representation of time in Unix-like operating systems, databases, server logs, and web protocols.
Our converter translates seconds, milliseconds, microseconds, and nanoseconds into ISO 8601 dates, GMT/UTC strings, RFC 2822 timestamps, and local timezone formats. You can also pick any date and time on an interactive calendar to generate its exact Unix timestamp integer in milliseconds.
Intelligently detects whether input integers are in seconds (10 digits), milliseconds (13 digits), or microseconds (16 digits) for seamless conversion.
Effortlessly convert Unix integers to human-readable dates, or pick calendar dates and times to generate precise epoch timestamps.
Features a live ticking counter showing the current Unix epoch second with one-click copy functionality.
All conversions run locally in browser memory. No database queries, server logs, or telemetry are ever generated.
Unix timestamps are widely used in databases and token authentication. Inspect JWT expiration timestamps with our JWT Decoder, format database queries containing timestamps using the SQL Formatter, generate unique database IDs with the UUID Generator, and convert general dates with the Timestamp Converter.
For API payloads, format JSON logs with the JSON Formatter, validate JSON schemas using the JSON Validator, test regex date parsers with the Regex Tester, and decode Base64 logs with the Base64 Decoder. Explore all utilities in the Developer Tools Suite.
Supports high-resolution distributed timestamps (16-digit microseconds and 19-digit nanoseconds) used in distributed tracing and telemetry systems.
Accurately converts UTC epoch seconds to your exact local timezone, accounting for Daylight Saving Time (DST) and regional timezone offsets.
In legacy 32-bit Unix systems, epoch time is stored as a signed 32-bit integer, which will overflow on January 19, 2038 at 03:14:07 UTC. Modern software engineering standards have transitioned to 64-bit integers, which can represent dates billions of years into the future. The Todoal Unix Timestamp Converter uses JavaScript 64-bit floating-point numbers and BigInt arithmetic to seamlessly calculate dates centuries beyond 2038 without integer overflow errors.
Relational databases (like PostgreSQL and MySQL) and distributed NoSQL datastores (like MongoDB and Redis) rely on Unix epoch integers for efficient indexing, time-series aggregation, and TTL expiration tracking. Converting raw epoch timestamps into human-readable ISO 8601 and local timezone strings ensures developers can analyze database records and audit access logs accurately.
