Конвертер временных меток

A Unix timestamp like 1751500800 is wonderful for machines and unreadable for humans. Anyone working in logs, databases or APIs keeps tripping over these numbers and wants just one thing: what date is this actually? This converter answers the question both ways - the number becomes a date, the date becomes the number.

Seconds or milliseconds - both units are supported, because some systems count seconds since 1 January 1970 while others count milliseconds. You switch, the tool computes accordingly. You see the result in several formats at once: ISO 8601, a human-readable date, the relative "three hours ago" and more, each copyable with one click.

Time zones are the classic source of errors. The converter shows a timestamp in parallel across fourteen important zones - from Berlin through UTC, London and New York to Tokyo, Shanghai and Sydney. So you can see at a glance when an event happened in California while you are looking at the clock in Germany, daylight saving included.

The math mode turns timestamps into a kind of calculator for time. Add days, hours or minutes to a timestamp or subtract them to find out when a deadline expires or when an event started. The duration mode measures the span between two moments and breaks it down neatly into years, months, weeks, days, hours, minutes and seconds.

If you work with many values, use the batch mode and convert a whole list of timestamps at once. Ready-made presets provide typical moments for quick testing, and the current time is always just one click away.

Everything runs locally in your browser. No timestamp and no date is sent to a server. The tool is fast, works offline and needs neither account nor signup - exactly right for a quick job you do in passing.
