Minutes to decimal hours conversion table

Pay period types and paychecks per year
Weekly pays 52 times a year, biweekly 26, semimonthly 24, and monthly 12. Biweekly (every two weeks) and semimonthly (twice a month) are not the same thing.

How many work hours are in a year?
A standard full-time year is 2,080 hours: 40 hours a week times 52 weeks. That 2,080 figure is the basis for a full-time-equivalent (FTE). Other schedules are in the table.

Time clock rounding rules (the 7-minute rule)
Rounding clock times to the nearest quarter hour is a long-standing payroll practice. The 7-minute rule: 1 to 7 minutes rounds down, 8 to 14 rounds up. It must be neutral and never consistently favor the employer.
