Daily Time Entries
Enable or disable each day of the work week (Mon–Sun) using the toggles. Disabled days are excluded from the calculation entirely.
Choose your lunch mode: "Manual" to enter specific lunch start and end times for each day, or "Auto-Deduct" to subtract a fixed lunch duration (e.g., 30 or 60 minutes) from the middle of each shift.
Enter your clock-in time and clock-out time for each enabled workday. If using manual mode, also enter your lunch start and end times.
Set the overtime threshold (default is 40 hours per week). Hours worked beyond this threshold are counted as overtime hours.
Click "Calculate Hours" to see a daily breakdown table showing hours before lunch, hours after lunch, lunch duration, and total hours per day, along with weekly totals including overtime.
The total work hours for a day are calculated by splitting the shift into two segments: the time from clock-in to lunch start, and the time from lunch end to clock-out. The lunch break period is excluded from paid hours. In auto-deduct mode, the calculator simply subtracts a fixed duration (e.g., 30 or 60 minutes) from the total shift time. Under the Fair Labor Standards Act (FLSA), employers are generally not required to pay for bona fide meal breaks (typically 30 minutes or longer), provided the employee is completely relieved of all duties during the break. Shorter breaks (usually under 20 minutes) must generally be compensated.
Clock in at 9:00 AM, lunch from 12:00 PM to 1:00 PM, clock out at 5:00 PM. Hours before lunch: 3.00h. Hours after lunch: 4.00h. Lunch duration: 1.00h. Total daily hours: 7.00h. Over 5 days: 35.00 total hours (all regular, no overtime since under 40h threshold).
A restaurant worker works 6 days: Mon–Sat, 10:00 AM to 6:00 PM with a 30-minute auto-deducted lunch. Total shift per day: 8h − 0.5h = 7.5h. Weekly total: 7.5 × 6 = 45.00 hours. Regular hours: 40.00. Overtime hours: 5.00. The overtime premium (at 1.5x) would apply to those 5 extra hours.
Mon: 8:00 AM–12:00 PM (4h, no lunch). Tue: 9:00 AM–5:30 PM with lunch 12:30–1:00 PM (before: 3.5h, after: 4.5h, total: 8.0h). Wed: 10:00 AM–6:00 PM with lunch 1:00–1:30 PM (total: 7.5h). Thu–Fri: same as Tue (8.0h each). Weekly total: 4.0 + 8.0 + 7.5 + 8.0 + 8.0 = 35.5 hours. All regular, no overtime.
