Sundays #bandofsketchers prompt was ‘date’ I was going to draw an old mechanical calendar  (one that you turn round to change the date) but I can’t find it. So then I decided to sketch a log, cut in half, to represent tree rings (dendrochronology) you can count the rings to find out the age of the tree and as the widths of the rings change with the weather you can also work out the years it was growing.
