Yes, the Unix Timestamp Converter is completely free to use. Convert between timestamps and human-readable dates as often as you need without any limitations or sign-up requirements.
Yes, all timestamp conversions happen locally in your browser using JavaScript's built-in Date functions. No data is sent to any server. The current time display updates in real-time using your device's clock.
A Unix timestamp (also called Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is a standardized way to represent time that is timezone-independent and widely used in programming, databases, and APIs.
Yes, the tool automatically detects whether your input is in seconds or milliseconds based on the number's magnitude. Timestamps greater than 9999999999 (roughly year 2286 in seconds) are treated as milliseconds. This means you can paste timestamps from JavaScript's Date.now() without manual conversion.
Unix timestamps are always in UTC (Coordinated Universal Time). When you convert a timestamp to a date, the tool shows both the UTC time and your local time based on your browser's timezone settings. When converting a date to a timestamp, local dates are interpreted in your timezone and converted to UTC.
