Question 1

What is 12×31?

Accepted Answer

12×31 is a free year planner app that displays all 12 months of your year in a single grid — 12 columns for months, 31 rows for days. It lets you see every trip, commitment, and free weekend at a glance, replacing the week-by-week view of traditional calendar apps.

Question 2

Is 12×31 free?

Accepted Answer

Yes. 12×31 is completely free to use with all features included. There is an optional one-time support payment of CHF 3 for people who want to support development — no subscription, no account required for the payment.

Question 3

Does 12×31 work offline?

Accepted Answer

Yes. 12×31 is a progressive web app (PWA) that works fully offline after your first visit. You can install it on your home screen on iOS, Android, or desktop. Events sync to the cloud when you're back online.

Question 4

Can I import events from Google Calendar or iCal?

Accepted Answer

Yes. 12×31 supports importing .ics files exported from Google Calendar, Apple Calendar, Outlook, and any other calendar app that supports the iCal format. Multi-year imports are supported.

Question 5

Does Google Calendar have a year view with events?

Accepted Answer

Google Calendar's built-in year view only shows a small grid of dates without any event details. 12×31 solves this — it displays all 12 months in a full-width grid with colour-coded event bars for every trip, meeting, and commitment. You can export your Google Calendar as an .ics file and import it into 12×31 to see your entire year at a glance.

Question 6

Which countries' public holidays are supported?

Accepted Answer

12×31 includes public holidays for 31 countries from A to Z, including the US, UK, Canada, Australia, Germany, France, Switzerland, Netherlands, and many more. Holidays are overlaid on the grid and can be toggled on or off.
