How many days in 1 million years?

Well there are 365 days in a normal year and 366 in a leap year. Leap years happen every 4 years (or there abouts).

So in 1 million years there will be 250000 leap years, leaving 750000 normal years

Thus 750000 * 365 = 273750000 days

250000 * 366 = 91500000 days

thus the total number of days in 1 million years is 365,250,000
