In the first 3 months of a leap year, there are 91 days. 31 + 29 + 31 = 91
= 365 x 3 + 1 = 1096 days

1096 days
A quarter of a year is 91,25 days or three months. Every leap year the quarter of a year is 91,5 days or three months.
January = 31 daysFebruary = 29 daysMarch = 31 daysSum = 91 days

In the first three months of a leap year, there are 31 + 29 + 31 = 91 days.
That depends on which year it is because of the leap years in February
Let us say that we start with January first. The first 9 months of the year (and assuming it is not a leap year) add up to 273 days. So you have 9 months and ten days.
1913 Days considering 1 leap year
Between 426 and 428 days. If leap year and these two months are July and August: 428 days If leap year and these two months are not a combination of July+August :427 days If not a leap year and these two months are July and August: 427 days If not a leap year and these two months are not a combination of July+August: 426 days
With the exception of leap years, 11 months have *at least* 29 days. In leap years all months have *at least* 29 days. February is the only month that ever has exactly 29 days, in leap years.
Assuming that they are consecutive months, this depends on which years are involved. 120 months is 10 years. That period must contain at least two, and possibly three, leap years. If there are two leap years then the answer is 3652, and if there are three then the answer is 3653.
36 calendar months is three years and will be 1095 days or 1096 if including a leap year February (29 days versus 28). In Julian years, 36 months is 1095.75 days.
In a leap year, there are 186 days in the 31 day months and 180 days in the other months, so that is a difference of 6 days.
