There is a chart on Wikipedia (in Japanese). Setsubun is on the 2nd in 2021 (令和3年) and the previous time was in 1897 (明治30年). Setsubun was on the 5th in 1984 and the next time is in 2104.
That chart for risshun is quite different from the English one, the four years I mentioned were on the 3rd February but observed in Japan on the 4th.
At least I have something to keep me challenged this lock down, it’s going to take me a while to get my head around all (or rather the pertinent parts of) this.
