How to use Convert Human Time to Unix Time
- 1. Paste your date-times. Enter one date-time per line in the format YYYY-MM-DD HH:MM:SS, treated as UTC, such as log timestamps or scheduled event times.
- 2. Read the epoch seconds. Each date-time converts to the number of seconds elapsed since 1970-01-01 00:00:00 UTC, so the epoch itself resolves to 0 on the matching line.
- 3. Copy the timestamps. Copy the resulting Unix timestamps and paste them into an API payload, database column or script that stores time as an integer.
When to use Convert Human Time to Unix Time
Convert Human Time to Unix Time turns readable UTC dates into the integer timestamps that databases, APIs and log files actually store. It is for anyone who has a calendar date in mind but needs the epoch number a system expects.
- Filling in an API request. An API endpoint accepts a 'created_after' parameter as a Unix timestamp, but you know the cutoff as a calendar date. Converting the date here gives the exact integer to paste into the request.
- Seeding a test database. A test fixture needs a column of expiry timestamps stored as epoch seconds, but the test plan is written as readable dates. Converting the list keeps the fixture readable in source yet correct on disk.
- Scheduling a cron-based job. A scheduler stores its next-run field as Unix seconds, and you want to set it to a specific date and time next quarter. This tool produces the number to hardcode into the config.

About the Convert Human Time to Unix Time tool
Convert Human Time to Unix Time runs as plain JavaScript in your browser tab, with no server behind it. Turn readable UTC date-times into Unix epoch timestamps (seconds since 1970). Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Time Tools section, 90 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. 2 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Convert Human Time to Unix Time free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
