Date to Unix Timestamp
About Date to Unix Timestamp
Date to Unix Timestamp converts a human-readable date and time into a Unix epoch timestamp. It supports any timezone and accepts ISO 8601 input as well as common formats.
How to use it
- Enter a date and pick a timezone. The timestamp appears below.
Common use cases
- Generating test fixtures. Cross-checking logs against application events.
Unix timestamps count the seconds since 1 January 1970 UTC, and they are how a great deal of backend code, databases and APIs store time. If you are building an API call, writing a test, or checking a record, you often need the opposite of the readability — a concrete date turned into its epoch seconds. This converter does exactly that, taking a date and time and returning the Unix timestamp in seconds.
It pairs naturally with the timestamp-to-date tool: this one moves the human-readable date into the form your code can use.
How to Convert a Date to a Timestamp
- Enter the date and time.
- Read the Unix timestamp in seconds that the converter produces.
- Copy the value into your code, request or test.
Practical Use Cases
Build a Unix timestamp for an API request or a code test, convert a scheduling decision into the numeric time a script expects, and mint specific timestamps to verify how a system stores or compares times.
Time Zone Matters
Unix timestamps are absolute — they reference UTC. The converter keeps that consistent, so the number you get is the correct epoch regardless of typical time zone differences of the input.
Date to timestamp — common questions
What exactly is an epoch timestamp?
It is the number of seconds that have passed since 1 January 1970 at 00:00 UTC. Systems use it as a compact, unambiguous way to store time.
Why is my converted date shown in UTC rather than my local zone?
Because a Unix timestamp is defined against UTC. Using that reference keeps the conversion correct and consistent wherever the value is later read.
Is a future date supported?
Yes, the converter accepts dates in the future as well as the past, giving the correct epoch seconds for whichever moment you specify.
