About

Converts a date into a Unix timestamp, useful for testing APIs and databases that use epoch time.

How to convert a date to a Unix timestamp

The converter turns a readable date and time into a Unix timestamp — the number of seconds since January 1, 1970. It is useful for generating values compatible with APIs, scheduling, and databases.

While humans read "November 14, 2023", systems and APIs prefer a single number like 1699920000. Converting to a timestamp removes timezone ambiguity and makes comparisons and calculations between dates easier.

The resulting timestamp represents the date in UTC. If you enter a date in your local timezone, the tool converts it to the UTC equivalent before calculating the value.

This format is ubiquitous in development: authentication tokens, task scheduling, caching, and logs use timestamps to mark time precisely and sortably.

Examples

  • Input: 2023-11-14 00:00 (UTC) → 1699920000
  • Converting the current date to a timestamp makes it easy to compare events before or after today.

Limitations

  • Dates before 1970 produce negative timestamps, which may not be supported by all systems.
  • Precision depends on the timezone provided; a timezone error can shift the result by hours.

Frequently asked questions

Is the result in seconds or milliseconds?

The standard Unix timestamp is in seconds. Some systems require milliseconds — just multiply the value by 1000.

How does timezone affect the result?

The timestamp is always in UTC. If you enter a date in another timezone, the tool converts it to UTC before calculating.

Do dates before 1970 work?

Yes, producing negative timestamps. However, some legacy systems do not support negative values.
