Counting to and from day 283

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 283 minus today's day 266 gives 17 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 10 in 2026 that is 273 days across the earlier months plus 10, giving 283. 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.
