Sometimes you need to create a recurring holiday (a holiday that repeats each year). In order to mark a holiday as recurring, in the setting section for holidays, make sure to enable "Recurring Holiday".
Recurring holiday does not require the year, it will happen on the given day every current year regardless of the year selected for dates. For example if you create a holiday for
02/03/2022 it will repeat on March 2nd of every year and not just for 2022.
