CALENDAR

Your own calendar, kept in your own browser. Add what you like, repeat it, and pull it in from — or push it out to — any other calendar as an .ics file. Nothing is uploaded and there is no account to make.

Upcoming

Nothing scheduled yet. Add an event, or load the demo below to see how it looks.

Birthdays

Add someone once and their birthday comes back every year, on its own, for as long as this calendar exists. Give the year they were born and each one shows the age they are turning. Underneath these are ordinary events — they show in every view, export to .ics, sync with your account, and can be edited or deleted like anything else.

No birthdays yet. Add one above and it will repeat every year.

Extra calendars

Days worth knowing about, drawn on the grid beside your own events. Everything here is worked out in this tab from the date rules themselves — it is never stored, never written into your .ics export, and never uploaded with the copy synced to your account. Tap one to see what it is, or to copy it in as an event of your own.

Canada is the federal set and the United Kingdom set is England & Wales — provincial, Scottish and Northern Irish days differ. Islamic dates use the tabular calendar and can fall a day either side of local moon-sighting. Space launches come from Mission Control and are fetched from there when the layer is on; nothing about you is sent.

Calendar file

Import a .ics export from Google Calendar, Apple Calendar, Outlook or anything else that speaks iCalendar, or export what is here to take it elsewhere. Both directions run in this tab — the file never leaves your machine.

Your account

Everything above is stored only in this browser. Turn this on and a copy of your events is kept against your Slippy Labs account instead, so the same calendar follows you to another device — and the next few events show up on the home page. It is off until you switch it on, and switching it off deletes the stored copy.
