A meaningless, incomplete holiday in Apple's US Holidays calendar

I show the US Holidays in my Calendar application, and there is one holiday there that is driving me nuts. Believe it was a mistake by the creator of the app and needs editing! On March 29, there are only these letters typed "Holi" Totally meaningless, takes up space on my calendar, as if the data entry person at Apple started to put an actual holiday there but gave up. Hope someone at Apple can fix this!
