Encl. (1) to COMDTINST 12550.3C
12 JUNE 1989
If an employee performs overtime services during the night hours at the beginning of the next
regular workday following a Sunday or holiday which overtime services are in continuation of an
assignment begun on the Sunday or holiday immediately preceding such regular workday, the
compensable time for the overtime services following such Sunday or holiday shall be the period
between midnight of such Sunday or holiday and the conclusion of the overtime services (e.g., if
work is from 11:00 p.mp Sunday to 2:00 a.m. Monday, compensable time is 2 days' pay for
Sunday, plus 1/2 day's pay for Monday). Overtime worked outside the hours of eligibility
identified in this instruction will be paid under the provisions of 5 U.S.C. or 29 U.S.C.
The compensable time for overtime service performed by an employee assigned to a regular tour
of duty covering any part of a night shall be computed in accordance with this rate as though the
beginning of the regular tour of duty of such employee marked the end of a night period and the
close of such tour marked the beginning of another night period. This would apply when the
regular tour of duty covers unusual hours, such as from 2:00 p.m. to 10:00 p.m. In this case,
compensable time is computed as follow:
The first 4 hours of compensable overtime are from 10:00 p.m. to 2:00 a.m.
After 2:00 a.m., the 4-hour "call back" overtime rule applies.
The total extra compensation paid pursuant to this instruction to an employee for overtime
service performed during one night shall not exceed 2 and 1/2 times the gross daily rate of the
Compensation for Sunday or Holiday Service.
The rate of extra compensation for Sunday or holiday services is hereby fixed at twice the gross
daily rate of regular pay of the employee who performs the service for any all services totaling an
aggregate of not more than 8 hours during the 24 hours from midnight to midnight of the Sunday
or holiday, including actual waiting time and time required for travel between posts of duty but
not including any period for meals or other time not spent at the post of duty. This rate shall
apply regardless of the length of time served within the aggregate of 8 hours, whether it is
served continuously or in broken periods, and whether it is served for one or more applicants.
Services in excess of an aggregate of 8 hours performed during the 24 hours of a sunday or
holiday shall be compensated on the same basis as overtime services performed at night on a
weekday, the time between the completion of the aggregate of 8 hours and midnight being
considered as the hours of a night (e.g., if an employee works continuously from 6:00 a.m. to
4:00 p.m. on Sunday, the rate of pay is 2 days' pay for Sunday, plus 1/2 day's pay for the period
2:00 to 4:00 p.m.).
