About
Time calculations, without the clutter.
Cloculator is a simple time calculator for working hours, flight durations, shifts and everyday schedules. Enter hours and minutes naturally, choose your mode and calculate.
No ads. No subscriptions. No tracking. One purchase.
DURATION
Add and subtract durations, or multiply and divide a duration by a number. See the result in hours and minutes, decimal hours and total minutes.
1:30 + 2:45 = 4:15
4.25 hours · 255 minutes
24-HOUR
Calculate across midnight while keeping track of the days. Enter durations longer than 24 hours and see where they take you.
21:00 + 4:00 = 01:00, +1 day
20:00 + 36:00 = 08:00, +2 days
SIMPLE BY DESIGN
• Natural hours-and-minutes entry with a dedicated :00 shortcut.
• Invalid minute digits are disabled as you type.
• Correct an operator before entering the next number.
• Familiar MC, MR, M+ and M− controls, with the stored value visible.
• A clean native interface with light and dark appearances.
• Works entirely offline. No account required.
Calculations run from left to right. Fractional minutes are rounded to the nearest whole minute and marked ≈; further calculations use the rounded value.
24-hour mode uses fixed 24-hour days. It does not calculate calendar dates, time zones or daylight saving changes.
