4 years (1996, 2000, 2004, 2008) have 29 days of February.
Implies 12 months of these 4 years have 29 days = 12 months × 4 years = 48 months (have 29 days in each month)
Balance years = 16 – 4 = 12 years
12 years have 11 months with 29 days. = 12 × 11 = 132
So, 48 + 132 = 180 (have 29th day in the month)
Hence, the answer is 180.
