A residents' welfare association meets on the last Thursday of every month. Using the January page shown, on which date is the March meeting?

1 January is a Friday. February starts 31 days later (+3): Monday; an ordinary February has 28 days, so 1 March is also a Monday. The March Thursdays are 4, 11, 18 and 25, so the last is 25 March. (26 March is the last Friday; 31 March is just the last day.)
