I have an array of 31 elements in Libreoffice Calc which I have to fill automatically with the days of the week (Mon, Tue, Wed, Thur, Fri, Sat, Sun, Mon, etc...) setting only the first element of the array (ideally with a dropdown menu).

How can I do that?


First place the days of the week in cells A1 through A7. This is the list we will use for Data Validation. Then put the Data Validation pull-down in cell B1. Pick any day.

In C1 enter:


In C2 enter:


and copy C2 downwards.

Finally in B2 enter:


and copy downwards:

  • you can pick any value from the pull-down to fill cell B1 and the rest will increment cyclically downwards
  • you can use this trick to propagate any cyclically repeating data. (like months, etc.)
