Fastest way to convert date and time to Unix timestamp on desktop and mobile.
Date to Timestamp
Date to Timestamp converter for turning date and time into Unix timestamp (seconds and milliseconds) with picker, manual fields, or text input.
Manual Fields

FAQ
Which input format should I use?
Use the date-time picker for speed, separate fields for precise manual entry, and text input when pasting formats like YYYY-MM-DD HH:mm:ss or ISO 8601.
Does this converter use my local timezone?
Yes. Date-time picker and separate fields are interpreted as local time. ISO 8601 text with timezone (like Z or +08:00) uses the timezone provided in that input.
What Unix outputs do I get?
You get Unix timestamp in seconds and milliseconds, plus local time, UTC (GMT), and relative time for validation.
Can I convert date-time values with timezone offsets?
Yes. Paste ISO 8601 values with timezone offsets, such as Z, +08:00, or -05:00, and the date to timestamp converter will normalize them to the correct Unix timestamp.
