How to use this calculator
Enter when the ticket opened, the target in service minutes and when to measure consumption. Choose service weekdays, daily hours, closures, time zone and pause intervals.
Only elapsed time within service windows consumes budget. Pauses outside those windows do nothing; overlapping pauses count once. Daily hours must open and close on the same date. Searches stop after 731 calendar dates.
A worked example
A 240-minute target opened Friday November 6, 2026 at 16:00, with weekday 09:00-17:00 service and a Monday 09:00-10:00 pause, is due Monday November 9 at 13:00.
Can I use this to interpret an SLA contract?
Enter the already-agreed service calendar and target. The calculator applies those rules but does not interpret contract language, priority changes or entitlement.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Most daily plans allow up to 366 dates; service-budget searches allow 731. Timed intervals have exclusive ends and use browser IANA time-zone rules; nonexistent local times are rejected and repeated times require your choice. Working calendars and policy terms are entered by you. The holiday comparison uses TimeCubby's published country/region coverage. Copy, CSV and print include assumptions; calendar exports appear when dated events exist.
