When you think about Setsubun, the date that comes to mind is the 3rd of February, but since this year's Beginning of Spring was moved due to the leap year, it became the 2nd of February (Setsubun is the day before the Beginning of Spring).
Fire at the oni! Fire at their clothes even more!
The 2nd of February is
The day of Setsubun!
Setsubun: A festivity celebrated at the end of winter (according to the Chinese calendar). The most memorable event related to this is probably mamemaki; which is throwing out soy beans as a means to drive the oni away.
