Formula
Total Minutes = Σ (Hours × 60 + Minutes)
Decimal Hours = Total Minutes ÷ 60
Decimal Days = Total Minutes ÷ 1,440
Example: (1h 30m) + (2h 45m) = 225 minutes → 3 hours 45 minutes → 3.75 hours → 0.1563 days.

- Roll up a week’s worth of meetings for billing.
- Track cumulative study time when prepping for exams.
- Plan workouts and rest intervals with precision.
- Summarize volunteer hours for reporting purposes.
Frequently Asked Questions
Can I enter decimals?
Enter decimals in the hour field if you like (e.g., 1.25 hours). Minutes should stay between 0 and 59 for clarity.
What about negative time?
You can subtract time by entering negative hours. The calculator will allow negative totals and display the sign accordingly.
Does the order of entries matter?
No—everything is added together. Reorder entries however you prefer for readability.
Can I export results?
Copy the totals into your spreadsheet or project tool. CSV export can be added later based on feedback.
