Missing timezone
A date without timezone may be interpreted as browser local time.
Date to Unix Timestamp
Convert readable date-time text into Unix seconds and milliseconds for APIs, logs, and database fields.
What this solves
Use this guide when you need a numeric timestamp from a date string, an ISO value, or a local time during debugging.
How to use it
- Prepare a clear date-time string such as an ISO value or YYYY-MM-DD HH:mm:ss.
- Open the main timestamp tool and paste it into the DateTime to Timestamp panel.
- Choose the timezone context before trusting the output.
- Copy seconds or milliseconds depending on the target system.
Date input example
2026-01-01 00:00:00 2026-01-01T00:00:00Z
The tool returns Unix seconds and Unix milliseconds for the same date-time input.
Use UTC input when the target API expects a timezone-independent value.
Common mistakes
Ambiguous date format
Prefer ISO or YYYY-MM-DD HH:mm:ss to avoid month/day confusion.
Wrong output unit
Check whether your API expects seconds or milliseconds before copying.
Date to timestamp FAQ
Can I use ISO date strings?
Yes. ISO strings are recommended when timezone clarity matters.
Should I copy seconds or milliseconds?
Use seconds for many backend APIs and milliseconds for JavaScript Date workflows.
Why did the result shift by timezone?
The same date text may be parsed in local time unless a UTC offset is included.
