This is probably a bit of a noob question, but I've been using a very (very!) simple sheet to keep track of the hymns we sing at our church, and how often, and that's been easy to set up. But what would be really helpful is another column that says when each hymn was last sung (so we know if it was sung only two weeks ago then we probably shouldn't do it again, but if it was 6 months ago or something then it's probably worth singing it again.)
I've attached the current table. This is probably a terrible way of recording this data and there's probably a far more efficient way of doing it, but it works for us at the moment! But if you were able to help fill in column C then I'd be very grateful.
