Options
Wrap after 24 hours
Pad output with zeros
Trim input values

How to Use:

  1. Enter the base time (e.g. 14:00:00) in the Start Time field.
  2. Enter the duration to add (e.g. 00:45:00) in the Increment by field.
  3. The updated time will appear immediately in the New Time field.
  4. Use the Options panel to customize:
    • Wrap after 24 hours rolls time around the next day.
    • Pad output with zeros ensures two-digit formatting for all units.
    • Trim input values removes spaces from pasted time values.

  6. Click Clear All to reset both fields and the output.

What Increment a Clock Time Tool can do:

This tool adds a time offset to any clock value you provide. The result is calculated in total seconds and converted back to a HH:MM:SS format with optional padding and wraparound. It supports both simple increments like 00:05:00 and longer spans like 03:45:30.

Example:

Start Time:

14:00:00

Increment:

00:45:00

Output:

14:45:00

Or, if the increment pushes past midnight and wrap is enabled:

Start: 23:30:00 + 01:00:00 → 00:30:00

Common Use Cases:

Use the Increment a Clock Time Tool for scheduling adjustments, workout timers, countdown builders, or event calculators. It’s ideal for developers, project managers, broadcasters, and anyone who works with durations and timestamps regularly.

Useful Tools & Suggestions:

If you’re letting users scroll through times or build sequences, Decrement a Clock Time complements it perfectly for moving backward. Together, they’re great for time input tools or event planners. And once the time’s locked in, Format a Clock Time ensures everything looks polished and consistent, no matter how much it’s been adjusted.
