A meeting every Monday, maintenance on the 10th, a birthday every year: enter it once and Jarbas repeats it for you.

How to create it

1. In the Calendar, create the event with its title, date and time.
2. In the Frequency field, choose how it repeats.
3. Under Ends, say how long for.
4. Save.

The frequencies

Do not repeat — a one-off event, the default.

Daily — every day.

Weekly — every week. The days of the week appear for you to tick: it can be Mondays only, or Monday, Wednesday and Friday on the same event.

Monthly — every month. You choose between two patterns:

• Day of month — always the 10th, for example.
• Occurrence and week day — always the first Monday, the last Friday, and so on. Use it when the date moves but the position in the month doesn't.

Yearly — every year on the same date.

Custom — when none of the above fits. You set Every how many days, weeks or months the event happens. Every 3 weeks, every 2 months. Choose weeks and you can still pick which days.

How long it repeats

The Ends field has three options:

• Never — repeats indefinitely.
• On a specific date — you pick the last day.
• Custom — you give a number of occurrences. E.g. 12 repeats and done.

For commitments with a fixed length (an 8-lesson course, a 10-session treatment), a number of occurrences is easier than working out the end date.

Day of month vs. occurrence

Worth understanding the difference, as it's the choice that confuses people most:

• The 5th of every month → lands on different weekdays. Good for payments, due dates, maintenance.
• The first Monday of the month → lands on different dates. Good for meetings, markets, shifts.

If you get a warning

• "Select at least one week day" — weekly repeats need at least one day ticked.
• "Enter a valid interval" — on custom, the "every" has to be a number above zero.
• "Enter a valid day of month" — the day has to be between 1 and 31.

To change it later

Editing an event that repeats raises an extra question: whether the change applies to that day only, from then on, or to the whole series. That's covered in the article on editing occurrences of a repeating event.
