Scheduling
Recurring dates, time slots, rotations and calendar files. Each tool has its own page. It runs in your browser, and it keeps its inputs in the address bar so you can share the answer.
The tools
Generate recurring dates, time slots and rotas, plan meetings and conferences across time zones, and export an event as an .ics file for any calendar app.
Meeting Time FinderAdd everyone's city, set the working hours, and see every hour of the next few days scored by how many people it suits — with the local time for each.
Best Meeting Time CalculatorPast four zones apart there is usually no hour that suits everyone. This ranks the compromises by who pays for them, so the choice is deliberate rather than accidental.
Recurring Date GeneratorDaily, weekly, monthly or yearly, with intervals and by-weekday rules — the dates listed with their weekdays, and the RFC 5545 RRULE beside them.
Appointment SchedulerA day divided into appointment slots of your chosen length, with buffers between them, breaks removed, and the whole grid copyable.
Event Duration CalculatorA start and a duration gives the end; a start and an end gives the duration. Both directions, with the time-zone and overnight cases handled.
Conference PlannerA run of sessions with their lengths and breaks, laid out in order, and then repeated in every attendee zone so nobody has to do the conversion themselves.
Time Slot GeneratorA start, an end, a slot length and an optional gap — and the resulting list of slots, numbered, with the leftover time at the end accounted for.
Availability CalculatorWorking hours minus the things already in them — the gaps left, how long each is, and how much of the day is genuinely open.
Rotation Schedule CalculatorA round-robin rota from a list of names and a shift length — day by day, with handovers marked and each person's total shown so the split is visibly fair.
Calendar Event GeneratorTitle, time, location, a reminder and an optional recurrence — out comes a valid .ics file to download, plus a Google Calendar link for people who will not.
