⏰ About Unix Timestamps
Unix timestamps represent seconds (or milliseconds) since January 1, 1970, 00:00:00 UTC.
- 10 digits = seconds since epoch
- 13 digits = milliseconds since epoch
- Widely used in databases, APIs, and logs
- 100% client-side processing for privacy

How to Convert Unix Timestamps
- 1
Choose Conversion Mode
Select whether you want to convert a Unix timestamp to a human-readable date, or convert a date to a Unix timestamp using the toggle buttons.
Tip:The tool automatically detects 10-digit (seconds) vs 13-digit (milliseconds) timestamps. - 2
Enter Your Input
For timestamp-to-date: Enter a Unix timestamp (e.g., 1703520000). For date-to-timestamp: Enter any valid date format (e.g., '2023-12-25', 'Dec 25 2023 14:30:00').
Tip:Use the 'Use Current' button to quickly insert the current Unix timestamp. - 3

Frequently Asked Questions
Is my data secure and private?
Absolutely! All processing happens entirely in your browser. Your timestamps and dates never leave your device.
What's the difference between 10-digit and 13-digit timestamps?
10-digit timestamps represent seconds since the Unix epoch (January 1, 1970), while 13-digit timestamps represent milliseconds. The tool automatically detects and handles both formats.
What date formats can I use for date-to-timestamp conversion?
You can use most standard date formats including ISO 8601 (2023-12-25), US format (Dec 25 2023), or with time (2023-12-25 14:30:00). The tool uses JavaScript's Date parsing, which supports a wide variety of formats.
How accurate is the current timestamp feature?
The current timestamp updates every second and shows both Unix and readable date formats. Copy it when you need the current time for a log, API request, or test.
Can I use this for different timezones?
The tool shows results in multiple formats: your local timezone, UTC, and ISO 8601. This makes it easy to work with timestamps across different timezones.
What is the Unix epoch and why is it important?
The Unix epoch is January 1, 1970, 00:00:00 UTC. It's the reference point for Unix timestamps, making it a universal standard for representing time in computing systems across different platforms and programming languages.
