How the numbers are worked out
1 January is day 1. Week numbers follow ISO 8601: weeks start on Monday, and week 1 is the week with the year's first Thursday.
Day of year = days since 1 January + 1
Days left = days in the year − day of year
Leap years
A leap year has 366 days because of 29 February. Years divisible by 4 are leap years, except century years not divisible by 400 (2000 was a leap year, 2100 won't be).
