The conversion factor from days to years is 0.0027379070069885, which means that 1 day is equal to 0.0027379070069885 years:

1 d = 0.0027379070069885 yr

To convert 564.4 days into years we have to multiply 564.4 by the conversion factor in order to get the time amount from days to years. We can also form a simple proportion to calculate the result:

1 d → 0.0027379070069885 yr

564.4 d → T_(yr)

Solve the above proportion to obtain the time T in years:

T_(yr) = 564.4 d × 0.0027379070069885 yr

T_(yr) = 1.5452747147443 yr

The final result is:

564.4 d → 1.5452747147443 yr

We conclude that 564.4 days is equivalent to 1.5452747147443 years:

564.4 days = 1.5452747147443 years
