@@girjashukla444 yes, if we consider 13th January Friday then the next Friday the 13th will be 13th April because January has 3 odd days feburary has 1 odd day(because of leap year) and March has 3 odd days. Then the total of odd days is 7 (3+1+3) therefore the next Friday the 13th will be 13 April. And the minimum number of days are 91.
@@jayeshdube8448 answer would be 28days if it is non a leap year. But in the given question it is mentioned leap year so 29 days is not divisible by 7. So, 30+31+30=91 days is minimum answer divisible by 7.
