If a leap year is included, two years is equal to 731 days. If no leap year is included, two years is equal to 730 days.
730 days for 2 normal years, 729 for 1 normal one leap years.
1yr=365day 2yr=730day
7,000 days is 19.16 years.
10 years = 3,652.4 days.
Assuming years of 365 days, 2190 days would be equal to six years.
