for libre office calc
Hello,
Not sure if this is a question or what it really means. Have you looked at Calendar Creator 2.0 template? See it here.
I think this question is actually pretty clear, even if brief.
In some cell, type the date you want to start from, eg 01/01/2018, or NOW(). Then in the cell below (or to the right, if you prefer), enter =A1+1 to get the next day (and fill this in the rest of the column, optionally breaking it (and changing the cell reference)). Then set the Format code in the Cell Formatting (CTRL + 1) to something like NN D MMM YY, so you can see the name of the weekend. And if you want to print this, maybe Format → Rows → Height and increase to 3 cm or so. If you want a monthly calendar, you can just use the formula =DAYSINMONTH(A1)+A1 instead. To have visible grid, make sure Grid is enabled in Sheet; or perhaps add borders instead.
