Reproducible worked example

Settings: No additional settings.

Input:

09:00,17:30,30

With the input and settings above, the tool produces:

Output:

{
  "elapsedMinutes": 510,
  "paidMinutes": 480,
  "paidDecimalHours": 8,
  "overnight": false
}

For this input, “elapsedMinutes” is 510; “paidMinutes” is 480; “paidDecimalHours” is 8; “overnight” is false. These are the named fields in the example output.

Limitations and common mistakes

  • Equal start/end means zero hours. Overnight shifts assume one midnight crossing and ignore daylight saving; payroll rules are not inferred.
  • Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
