Formula / Rule / Type 1 :-
Direct Formula / Rule 1 : Theorem : To find the day of a week by the help of the number of odd days, when reference day is given:Suppose a question like "Jan 1, 1992 was a Wednesday What day of the week will it be on Jan 1, 1993"? If you recall, 1992 being a leap year, it has 2 odd days. So the required day will be two days beyond Wednesday, that is, it will be 'Friday'. Working Rule (i) Find the net number of odd days for the period between the reference date and the given date. Exclude the reference day but count the given date for counting the number of net odd days. (ii) The day of the week on the particular date is equal number of net odd days ahead of the reference day (if the reference day was before this date) but behind the reference day (if this date was behind the reference day). Example :
1 = Friday |
