Understanding the Lunch Break Formula
The calculator follows a straightforward time calculation process.
Formula 1: Lunch Start Time
Lunch Start Time =
Work Start Time + Hours Worked Before LunchExample:
8:00 AM + 4 Hours
= 12:00 PMLunch starts at 12:00 PM.
Formula 2: Lunch End Time
Since the lunch duration is fixed at 30 minutes:
Lunch End Time =
Lunch Start Time + 30 MinutesExample:
12:00 PM + 30 Minutes
= 12:30 PMFormula 3: Shift End Time
The calculator assumes the lunch break is unpaid and extends the total shift by 30 minutes.
Shift End Time =
Work Start Time + Shift Length + 30 MinutesExample:
8:00 AM + 8 Hours + 30 Minutes
= 4:30 PMFormula 4: Total Paid Working Hours
Paid Working Hours =
Shift LengthExample:
8 HoursThe lunch break is not included in paid working time.
