Input Data
For timestamp conversion: Enter the timestamp value (10 or 13 digits).
For date/time conversion: Select or enter the date and time.
Select Format Options
Choose your preferred format:
- Timestamp Type: Seconds (10 digits) or milliseconds (13 digits)
- Date Format: Various display formats for date/time
- Timezone: UTC or local time conversion

- Use UTC timestamps for cross-timezone applications
- Consider timezone differences when converting historical data
- Validate timestamp ranges for your specific use case
Important Notes
- Unix timestamps start from January 1, 1970 (Unix epoch)
- Millisecond timestamps provide higher precision for modern applications
- Some systems may use different epoch dates (e.g., Windows FileTime)
- Timezone conversion may affect historical dates due to daylight saving time
Q: What is the difference between 10-digit and 13-digit timestamps?
A: 10-digit timestamps represent seconds since Unix epoch, while 13-digit timestamps represent milliseconds. 13-digit timestamps provide millisecond precision.
Q: Why do some timestamps show different dates?
A: This can be due to timezone differences or different epoch dates. Our tool uses the standard Unix epoch (January 1, 1970 UTC).
Q: How accurate is the conversion?
A: The conversion is mathematically precise. Any differences you see are likely due to timezone handling or display format preferences.
Q: Can I convert future dates?
A: Yes, you can convert any valid date/time, including future dates. The tool handles dates from 1970 onwards.
