58. One year of service or part of a year of service is credited, for each calendar year, to an officer for service accomplished if his contributions have been paid and not reimbursed and for service otherwise credited to him under the provisions of the plan. The same applies to an officer who has at least 35 years of credited service, without his having to pay contributions.
Service is credited according to the number of days and parts of a day for which the officer contributed or was exempt and the days or parts of days otherwise credited to him out of the number of contributory days in a year, that is, 260 or, as the case may be, 200, according to the basis of remuneration. If, in the total number of days and parts of days, there remains a part of a day less than 0.5, that fraction is cancelled; if the fraction is equal to or greater than 0.5, it is considered a full day.
