What about this idea for a calendar: every year is 1 month, every month is 1 week, and every week is 1 day?

- Every year and month starts on a Monday

- No leap days needed at all

- You can use the same calendar every year (better yet, you might already have a blank piece of paper you can use)

- Every day is your birthday

You might be responding tongue-in-cheek, but you have essentially described an underspecified variant of FDN Rata Die [1].

FDN R.D. does have a place in calendrical calculations; namely, it serves as the narrow waist for converting between calendars.

All the best,
