How to use this calculator
Enter the planning range and machine-day hours, then list machines and their first available dates. Add batches in the required order with a machine name, quantity, hourly rate and setup minutes.
Each batch occupies one uninterrupted daily window. Setup applies to every batch and run time rounds up to a whole minute. Machines run independently. An unfilled batch blocks later work on that machine so the queue cannot silently skip required work.
A worked example
A 100-unit batch at 50 units per hour plus 30 minutes setup occupies 09:00-11:30. A following 150-unit batch with 15 minutes setup ends at 14:45.
Will a batch continue automatically across overnight closures?
No. This version schedules uninterrupted batches. If one does not fit, extend daily hours or divide it into explicit smaller batches with the appropriate setup rules.
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.
