Here's May 2023's event calendar. Again, I've tailored it to reflect where I am from and also include the local area where I work. Therefore, you might want to edit it to more closely reflect you.
The students like the chōjū-giga illustrations so I decided to keep using them. I included Hawthorn and Lily of the Valley flowers since they are May's birth flowers and added some Wisteria as well simply cause it grows around this time of year in Japan and I think they are beautiful. :)
