Time Formatter
Format a time in multiple ways — 24-hour, 12-hour AM/PM, epoch seconds, ISO 8601, and written-out words — live as you type.
Enter Time

How Does It Work?
Enter hours, minutes, and seconds, then choose between 12-hour (AM/PM) or 24-hour format. The tool instantly converts your time into five formats: 24-hour HH:MM:SS, 12-hour h:mm:ss AM/PM, epoch timestamp in seconds since midnight, ISO 8601 string, and a human-readable words format.
Example
Entering 3:15 PM produces:
24h: 15:15:00 | 12h: 3:15:00 PM | Epoch: 54900 | ISO: 1970-01-01T15:15:00Z | Words: three fifteen pm
Common Use Cases
- Converting between 12-hour and 24-hour time formats for international coordination.
- Getting Unix epoch timestamps for midnight-relative time calculations.
- Generating ISO 8601 time strings for API payloads and log entries.
- Writing time in words for accessibility or natural-language UI elements.
FAQs
What is an epoch timestamp?
An epoch timestamp is the number of seconds elapsed since midnight UTC on January 1, 1970 (the Unix epoch). This tool calculates the offset from midnight for the entered time, not the full date-based timestamp.
Does this handle midnight (00:00 or 12:00 AM)?
Yes. In 24-hour format, midnight is 00:00:00. In 12-hour format, it displays as 12:00:00 AM.
Why use words format?
The words format is useful for screen readers, voice assistants, natural-language text, and any UI where a human-friendly time display is preferred over digital notation.
