Convert date to unix timestamp online

APIs, cron schedulers, and ORMs often expect a unix timestamp instead of a formatted string. When you convert date to unix timestamp, you turn a wall-clock moment into the integer seconds or milliseconds most systems store internally.

This date to epoch converter is useful for seeding test data, writing migration scripts, or checking what integer MongoDB or PostgreSQL will persist for a given datetime. Everything runs client-side — paste results into tickets without sending calendar data to a third party.

Select date and time with the datetime-local picker. The tool immediately shows unix seconds, unix milliseconds, and ISO UTC in a two-column output grid. Copy whichever format your stack expects.

Timezone matters: the picker interprets input in your browser's local zone. A meeting at 15:00 in Asia/Kolkata produces a different epoch integer than 15:00 in America/New_York. Document which zone you used when sharing numbers with teammates.

To convert time to unix timestamp for a UTC-specific value, mentally offset or use our Time Zone Converter after generating the local result.

MongoDB date to unix timestamp comparisons often use Math.floor(date.getTime() / 1000). PostgreSQL unix timestamp columns frequently store seconds. Python unix to datetime and the reverse use datetime.fromtimestamp and .timestamp().

Snowflake convert unix timestamp to date and the inverse appear in analytics pipelines — verify whether your warehouse stores seconds or milliseconds before pasting into production SQL.

Human date to timestamp workflows in support teams start here: pick the customer's reported local time, copy seconds, and compare against raw log integers on the Unix Time to Date page.

Unix seconds are ten digits for modern dates; milliseconds add three digits. APIs like Stripe timestamps often use seconds. JavaScript Date.now() returns milliseconds — double-check your SDK docs before inserting values.

ISO 8601 output ends with Z for UTC, which disambiguates storage format in JSON payloads. Pair unix seconds with ISO when writing API docs or runbooks.

Calendar picks for unreleased features or customer incidents stay on your machine. Clear the picker on shared computers when done.

Use Unix Time to Date to decode log integers back to readable clocks. Use Time Zone Converter when you need the same instant expressed in two global regions.
