I am trying to create an excel formula that will increment as the year changes. The following is what i am trying to do:

I have 2 columns - date and id. What i would like to do is increment the ID column by +1 when the year changes in the date column. So, dates from the same year will get the same id. (i am not concerned by the month/day values, all i need to do is assign the same id to dates from the same year).
I have tried a variety of formulas in excel but my excel skills are not great and i have been unable to find a solution. The best i could come up with is: IF(YEAR(A1=1928),420) but that would be quite monotonous to do for every year in the excel file.
i did try to do a bit of research and the only similar question that i could find on here was this --> Increment number when Date changes
Any help would be much appreciated
