Cirno Day 2024 Calendar. The magical day prophesied to come every 9,999 days on the great fairy calendar; Chose a month to view an observance and holiday calendar for that month in 2024.
For example, september 9 is cirno day (and also my sister’s birthday, too) because of cirno’s association with the number 9, and october 4 is tenshi day because “four” in. We just somehow managed to get it the whole thing made in 3 days.
