Hours Calculator

Free Hours Calculator. Calculate daily timesheet work hours, gross pay, break deductions, overnight shifts, and weekly overtime hours with ease.

Tool Overview & Core Functionality

Computes daily working hours, unpaid meal break deductions, overnight graveyard shift crossings, and gross payroll compensation.

              FLSA Employee Timesheet and Payroll Hours Algorithm:
            
              Net Hours = Shift End - Shift Start - Unpaid Break Duration

This calculator executes instantaneous, zero-latency computations strictly client-side. No financial balance, health metric, or personal chronological details are transmitted to external servers.

Admin Practical Note: The 7-Minute Payroll Rule

FLSA 15-Minute Increment Rounding Rules

Minutes 1 to 7: Rounds down to the previous quarter hour
Minutes 8 to 14: Must round up to the next quarter hour

Admin Practical Takeaway: Employers using 15-minute rounding must apply the rule symmetrically. Rounding down on clock-ins while rounding down on clock-outs violates federal wage law.
