How many odd dates are there in a year?

Answer 1

In a non leap year, there are 7 months with an odd number of days, if we exclude those 7 days you would have the same number of even & odd days. The formula will be:

(Total numbe of days - 7 ) / 2 = even number of days

( 365 - 7) / 2 = 179

Now you need to add back the days you excluded and you have the odd number of days. 179 + 7 = 186

In a leap year, you need to add one to that, so it is 187.
