I’m trying to display the days in which a certain volunteer has come, as a percentage of the days that have passed this year. I’d like that to be shown in a block, i.e. 33.1% of days Volunteer X has been present, (178 days this year, X has been here for 59 of them). How can I create such a block? How can I create a column which counts the days of the year that have passed?
