What is a Non-Leap Year
A non-leap year is a common year in the Gregorian calendar that has 365 days. It is called a “non-leap year” to distinguish it from a leap year, which has 366 days.
Characteristics of a Non-Leap Year
Number of Days: A non-leap year has 365 days.
Months and Days:
The distribution of days across the months is as follows:
- January: 31 days
- February: 28 days
- March: 31 days
- April: 30 days
- May: 31 days
- June: 30 days
- July: 31 days
- August: 31 days
- September: 30 days
- October: 31 days
- November: 30 days
- December: 31 days
Frequency: Non-leap years occur three out of every four years in the Gregorian calendar.
Determination: A year is a non-leap year if it is not evenly divisible by 4, except for years divisible by 100 but not by 400.
For example, the years 1900 and 2100 are non-leap years because they are divisible by 100 but not by 400, while the year 2000 is a leap year because it is divisible by 400.

Find the Probability of getting 53 Sundays in a Non-Leap Year?
Probability of getting 53 Sundays in a non-leap year is 1/7 or approximately 0.1429.
To find the probability of getting 53 Sundays in a non-leap year, we divide the number of non-leap years with 53 Sundays by the total number of non-leap years. Since each year has 52 weeks and 1 day, for 53 Sundays to occur, the year must start on a Sunday. In a non-leap year, this happens once every 7 years. So, the probability is 1/7.
Probability = Number of Favorable Outcomes / Total Number of Events
Here, Number of favourable outcomes = 1
Total number of events = 7
So, Probability = 1/7
Thus, the probability of getting 53 Sundays in a non-leap year is 1/7.
