## Changes Made

adds `day_of_year` to get the ordinal day 

## Note for Reviewers

the OP requested this to be called `ordinal_day`, but many engines call
this `dayofyear`, which I feel fits better with our current naming (e.g.
`day_of_week`). They both do the same thing though. (The day 1-366
(january 1st - dec 31st with optional leap day))
