How the calculator works
Total time equals the duration of one task multiplied by how often it occurs. Current and new frequencies are normalized independently, so a task may take longer each time but still save time overall when it happens less often.
Repeated intervals count one occurrence after each completed interval. For example, every 15 minutes during an 8-hour window means 32 occurrences—not an extra occurrence at time zero. A constrained daily schedule uses the active days per week you enter.
Calculation assumptions
- 24 hours per day and 7 days per week
- 365 days per year
- An average month of 365 ÷ 12 days (about 30.4167 days)
- No hidden rounding in calculations; displayed durations are rounded to the nearest second
