Unix Timestamp to Date Converter
Decode epoch seconds or milliseconds into readable dates
Current Unix Epoch Time
Unix → Human
Auto-detects seconds, milliseconds, microseconds, or nanoseconds
Overview
Convert a numeric Unix epoch into readable local time, UTC, ISO 8601, day-of-week, and relative-time values. The converter detects seconds, milliseconds, microseconds, or nanoseconds from the digit length, so logs and API payloads can be inspected without guessing their precision.
How It Works and Key Features
Paste a timestamp such as 1700000000. Precision is detected automatically, and every supported date representation appears immediately. Compare UTC with your browser-local display, then copy the exact format you need; the original value is never uploaded.
Examples and Use Cases
Decode JWT exp and iat claims, inspect database created_at values, correlate incident logs, or verify webhook event times. For example, 1700000000 seconds resolves to 2023-11-14T22:13:20Z and can also be copied at millisecond precision.
Edge Cases and Limitations
Input must be non-negative digits. Seconds are limited through year 2100, while longer values are interpreted by digit length. JavaScript dates are millisecond-precise, so microsecond and nanosecond outputs are derived values; local display also depends on the browser timezone and locale.
Reverse Conversion
Need to create an epoch value from a calendar date instead? Open Date to Unix Timestamp, choose the date, time, and IANA timezone, and copy the required precision.
