Calculating frequency of Earths orbit

Question

If the Earth takes one year to orbit the sun and the frequency is f = 1/T with T being the period.

Then what would the period be ? I am use to dealing with seconds and minutes but this question involves a year.

Answer 1

$T={1\over f}=1 year=365day*24{h\over day}*60{min\over h}*60{s\over min}=31536000s\approx3.15*10^7s$
