Getting a Day Number of the Year, while IGNORING leap years days (1-365, repeated)

I'm trying to get day number of the year to take an average of EVERY Jan. 1, Jan. 2, etc etc.

To do this Im trying to set up day numbers 1-365 repeated throughout the data frame for the multiple years.

I'm sure there are multiple ways to do this, but I'm getting a little stuck.

So far I've tried yday(df$Date) but it tries to add 366 days for leap years. I've removed ALL leap days from my data set, so this turns out false.

Any advice on how to proceed?

I think I figured it out

df$DayNumber <- rep(c(1:365), times = #YEARAMOUNT)

I'm sure there is a more elegant way that actually ties together the date and day number directly... but it seemed to work for my purposes.
