There are 366 days in a leap year, i.e, 1 more than a normal year. That means that we already have 52 sundays for sure. Then, we are left with 2 days. Now, these days can be any from a pair of- mon-tues,tues-wed,wed-thurs,thurs-fri,fri-sat,sat-sun,sun-mon.
Now, to get exactly 52 sundays, none of the last two days should be a Sunday. As you can see from the combinations listed above, that is possible in 5 out of 7 cases. So the Probability would be 57.
∴ Probability of leap year with 53 Sundays is 2/7.
there can be 53 sundays in a leap year if that one extra day is a sunday. Therefore, the maximum number of sundays in an random year is 53. There is no way a leap year can have 54 sundays.
As there are 52 weeks and 1 day in a non-leap year and 52 weeks and 2 days in a leap year. Thus, there can be definitely 52 Sundays in a year.
In a year we have 53 Sundays only when year start with Sunday (For non leap year) and either with Saturday of Sunday (For leap year).
A leap year has 366 days or 52 weeks and 2 odd days. The two odd days can be {Sunday,Monday},{Monday,Tuesday},{Tuesday,Wednesday},{Wednesday,Thursday},{Thursday,Friday},{Friday,Saturday},{Saturday,Sunday}. So there are 7possibilities out of which 2 have a Sunday. So the probability of 53 Sundays is 2/7.
The chances of being born on leap day are so rare that less than 0.1 percent of the world's population is born on February 29.
What is the rarest birthday? The least common birthday is leap day, or February 29. But because the day only occurs once every four years, it's obvious it would yield the least amount of birthdays. The rarest birthday of the 365 annual calendar days is Christmas Day, Dec.
It is unlucky to get married on a leap year, or tie the knot on a leap day! The Greeks and Italians believe that marrying on a leap day will lead to bad luck. The Greeks believe that most marriages celebrating that anniversary will lead to divorce.
The probability of a leap year having 53 Sundays is 2/7.
So, to get 53 Tuesdays, we have to select one more Tuesday from these 7 possibilities with Probability 17. Hence, favourable outcomes =2 and total outcomes = 7. Therefore, probability of having 53 Tuesdays in a leap year is 1×27=27.
Hence the probability of getting 53 sundays = 1 / 7.
In a non-leap year there will be 52 Sundays and 1day will be left. This 1 day can be Sunday, Monday, Tuesday, Wednesday, Thursday,friday,Saturday, Sunday. Of these total 7 outcomes, the favourable outcomes are 1.
There are 52.142857 weeks (52 weeks and 1 day) in 365 days (calculated as 365/7 = 52.142857). As a result, there are 52 Sundays in a non-leap year.
Hence there will be 52 Sundays for sure. 52 weeks \[ = {\text{ }}52 \times 7 = 364\] days . \[365-364 = 1\] day extra. In a non-leap year there will be 52 Sundays and 1day will be left.
In UK law, leaplings become a year older not on 28 February but 1 March. This could be something of a disappointment to a soon-to-be-17-year-old leapling planning a first driving lesson on 28 February - or to one turning 18 who was planning a rite-of-passage night on the tiles.
February 3rd is the only day where no one in history has ever been born. Despite much scientific study, there is no explanation for this phenomena. Historically it has been referred to as "the empty day" or "nobody's birthday".
People born on leap day are often called "leaplings" or "leapers." Most of them don't wait every four years to celebrate their birthdays, but instead blow out the candles on Feb. 28 or March 1.

Believe it or not, dozens of celebrities and public figures made their arrivals into the world on leap days, dating as far back as Pope Paul III in 1468 and as recently as NBA player Tyrese Haliburton in 2000.
Probability of 53 Sundays and 53 Mondays, is 17.
Because we know 52 Mondays counted in total for a full week in a year, so we need 1 more Monday which we have to take from the remaining 2 days.
This 1 day can be Sunday, Monday, Tuesday, Wednesday, Thursday,friday,Saturday, Sunday. Of these total 7 outcomes, the favourable outcomes are 1. Hence the probability of getting 53 sundays = 1 / 7. ∴ probability of getting 52 sundays = 1 - 1/ 7 = 6 / 7.
