The /etc/acct/holidays file describes which hours are considered prime time and which days are holidays. Holidays and weekends are considered non-prime time hours. /etc/acct/holidays is used by the accounting system.
All lines beginning with an "*" are comments.
The /etc/acct/holidays file consists of two sections. The first non-comment line defines the current year and the start time of prime and non-prime time hours, in the form:
current_year prime_start non_prime_start
The remaining non-comment lines define the holidays in the form:
Of these two fields, only the month/day is actually used by the accounting system programs.
The /etc/acct/holidays file must be updated each year.
