What Are Calendar Questions? Basic Concept in Simple Words
A week has 7 days. Because the number of days in a year or a month is not a multiple of 7, we use the remainder after dividing by 7. This remainder is called the number of odd days, and it tells us how many days the weekday shifts forward.
- Odd days = (number of days) divided by 7 and take the remainder.
- Weekday codes: Sunday = 0, Monday = 1, Tuesday = 2, Wednesday = 3, Thursday = 4, Friday = 5, Saturday = 6.
- To find the day of a date, find the total odd days from a known date and move forward by that many days.

- Leap year rule: a year divisible by 4 is a leap year, except century years, which must be divisible by 400. So 2024 and 2000 are leap years, but 1900 and 2100 are not.
- Same date, next year: the day moves forward by 1 for an ordinary year and by 2 if the leap day (29 February) falls in between.
- Repeating calendar: an ordinary year repeats after 6, 11 or 12 years (depending on leap years in between). A leap year repeats after 28 years (within the same century).
- Last day of a century can only be Monday, Wednesday, Friday or Sunday. It cannot be Tuesday, Thursday or Saturday.
- Days in x weeks: any number of days that is a multiple of 7 gives the same weekday.
- Extra day in a year: in an ordinary year, the weekday of 1 January also appears 53 times. In a leap year, the weekdays of 1 January and 2 January appear 53 times.
