How this calculator works
Estimate how many times a cron job runs per day, week, or month. Planning estimates only — verify with production tools and vendor pricing where applicable. Daily runs = (hours active) × (minutes active per hour); monthly ≈ daily × 30. Example: Every 15 minutes, 24/7 → 96 runs/day, ~2,880/month.
Daily runs = (hours active) × (minutes active per hour); monthly ≈ daily × 30.
Example: Every 15 minutes, 24/7 → 96 runs/day, ~2,880/month.
When to use this Cron Job Schedule
Common use cases
- Estimate how many times a cron job runs per day, week, or month.
- Sanity-check with this case: Every 15 minutes, 24/7 → 96 runs/day, ~2,880/month.
- The relationship is: Daily runs = (hours active) × (minutes active per hour); monthly ≈ daily × 30.
Localized examples
- Software Development & Programming: the example on this page uses the same formula as the widget.
What you get
- Fields: Run interval (minutes), Active hours per day, Active days per week
- Daily runs = (hours active) × (minutes active per hour); monthly ≈ daily × 30.
- Example on the page: Every 15 minutes, 24/7 → 96 runs/day, ~2,880/month.
How to Calculate Cron Job Schedule Step-by-Step
- 1Enter Run interval (minutes), Active hours per day, Active days per week. Use the values you have, not a catalog average, unless that is all you know.
- 2Daily runs = (hours active) × (minutes active per hour); monthly ≈ daily × 30.
- 3Worked case: Every 15 minutes, 24/7 → 96 runs/day, ~2,880/month.
- 4Compare the result to last month’s invoice or a vendor calculator before you commit capacity.
Governing formula
Daily runs = (hours active) × (minutes active per hour); monthly ≈ daily × 30.
Every 15 minutes, 24/7 → 96 runs/day, ~2,880/month.
Example: set Run interval (minutes) = 15, Active hours per day = 24, Active days per week = 7, then read the result.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
