One moment. Every format.
Convert Unix timestamps and ISO dates with explicit units. See UTC and your browser’s local time without guessing what a number means.
Signed whole integers for Unix units. ISO input requires seconds and Z or an explicit ±HH:mm offset.
Enter a timestamp or ISO date.
Choose units explicitly
Unix seconds and milliseconds are measured from 1970-01-01T00:00:00Z. Select the correct unit before converting. Zero is valid; negative values represent earlier moments. Input digit count never selects units automatically. Integer Unix input only; use milliseconds for sub-second precision.
ISO input and timezones
Use a four-digit year and YYYY-MM-DDTHH:mm:ss, optionally followed by 1–3 fractional-second digits, then Z or ±HH:mm. Example: 2024-02-29T12:30:00+02:00. Missing zones, impossible dates, 24:00 and leap-second :60 inputs are rejected. Calendar checks use the Gregorian leap-year rule.
UTC and ISO outputs describe the same instant. Browser-local output applies that browser’s configured timezone and daylight-saving rules, not a timezone inferred from the input or your physical location. No timezone selector is included in this release.
Precision and range
Dates use whole milliseconds. Unix seconds output rounds down, so −1 millisecond gives −1 second. Supported numeric dates stay within JavaScript’s ±8,640,000,000,000,000 millisecond range and safe integer limits. ISO input years are 0000–9999; numeric inputs can produce expanded-year ISO output. UTC date strings omit fractional milliseconds; use ISO or milliseconds when those matter.
Results, copying and errors
Changing input or mode clears previous results. Invalid input shows an error instead of leaving an old date visible. Each output has its own Copy button with manual selection fallback. Clear removes this page’s value and outputs, not clipboard history.
Release note
Version 1.0.0 extracts the legacy Date-based converter into an independent bilingual plugin. Preserves Unix/UTC/ISO/local outputs and current-time capture. Replaces digit-count guessing and permissive date parsing with explicit units and validated timezone-aware ISO input; adds negative timestamps, errors, stale-result clearing and copy controls.
