Days of the week repeat every 7 days. To jump forward any number of days, divide by 7 and move on only by the remainder. Count the days in each month, and remember the leap year rule for February.
Harder, multi-step puzzles for strong students and competitive exams: the same date many years later (count the leap days), century years that are NOT leap years (1700, 1800, 1900, 2100), the next year with exactly the same calendar, and the last weekday of a month.
A normal year moves a date on by 1 weekday; a 29 February in between adds 1 more.
Century years are leap years only if they divide by 400: 2000 yes, 1900 and 2100 no.
A calendar repeats when 1 January falls on the same day AND both years are leap (or both not).
