Counting to and from day 300
Ordinal day numbers make in-year arithmetic trivial: the gap between two dates in the same year is just the difference of their day numbers. Day 300 minus today's day 266 gives 34 days, with no month lengths to reason about. That is exactly why batch codes, expiry stamps and flight schedules use them.

Reading the number back
To go the other way, from a calendar date to a day number, add up the lengths of the months before it and then add the day of the month. For October 27 in 2026 that is 273 days across the earlier months plus 27, giving 300. The only wrinkle is February, which is why the same date can carry two different day numbers depending on whether the year is a leap year.
