How to use this calculator
Enter the start, period length and unit. For day periods choose whether the start counts, then specify the cutoff clock time, zone and how early you want to act.
Month periods use a clamped calendar-month anniversary. Day periods follow the chosen day-1 rule. The safety lead subtracts elapsed hours from the resolved cutoff, so local clock hours can change across daylight saving.
A worked example
A 14-day trial starting November 1, 2026 with the start as day 1 ends November 14. With a 23:59 New York cutoff and a 24-hour lead, act by November 13 at 23:59.
Does this cancel my subscription?
No. It creates a planning reminder using the terms you enter. Check the provider's actual cancellation process, processing time and cutoff before relying on that reminder.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Daily attendance, office, coverage and chore plans allow up to 366 dates; school cycles, course plans and milestones allow up to 731. Dependency and historical workday calculations scan at most 3,661 dates. Class-session searches allow 366 dates and 200 sessions. Time-zone tools use browser IANA rules and require a choice when local times repeat. Dates and policy rules are entered manually; no employer, retailer, school or local weather policy is inferred. Copy, CSV and printing include the calculation rules; calendar exports appear when the result contains dated events.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
