How to Use:

  • Start by pasting or typing your timestamps line by line into the Input Timestamp box.
  • The Trim input lines toggle is on by default it automatically removes extra spaces from each line. If you want to keep spacing exactly as entered, you can turn this off.
  • If your input contains any invalid or blank lines, the tool will include the word Invalid unless you turn on Ignore invalid timestamps, which skips them entirely.
  • Use the Maximize output toggle if you’re working with large datasets or want more space to view results. It stretches the output box vertically.
  • You can also click Convert to manually trigger a refresh, though the tool updates live as you type.
  • Hit Copy Output to copy the result to your clipboard. The button shows “Copied!” briefly and resets, even if you click it repeatedly.
  • Click Export to File to download your results as a .txt file.
  • To bring in data from a file, click Choose File under the input box. Supported formats include .txt, .csv, .tsv, .json, .log, and more.
  • Click Clear All to reset everything input, output, filename, and toggle states.

What Convert Timestamp to Hours can do:

This tool converts timestamps from just about any common format into whole hours. It understands clean timecodes like 00:45:00, datetime strings like 1970-01-01 01:00:00, ISO formats like 2024-01-01T12:00:00Z, and even human-readable dates like July 28, 2025 12:30. Behind the scenes, everything is normalized to UTC to keep your results consistent and timezone-safe.

When the input has full date and time, the tool calculates total hours since the Unix epoch. For time-only formats, like HH:MM:SS, it simply calculates how many hours are in that span. It’s smart enough to skip bad input when told to, and gives you fast, exportable results you can use right away. You can copy, save, or import your data, and it all works instantly in your browser without needing a refresh.
