are converted into years and days on the assumption that a year contains 365 days.
(5) If service is referred to as service in years–
(a)the days referred to in paragraph (2); and
(b)the full days referred to in paragraph (3),
are converted into years by dividing the number of days by 365, and using the result to 4 decimal places.
