Days in 8 decades

Calculating the days in 8 decades is a straightforward process:

1. Identify the time period:
   8 decades
2. Convert decades to days:
   8 decades × 10 years/decade × 365.25 days/year = 29220 days

   Note: A decade is 10 years, and we use 365.25 days per year to account for leap years.
