자주 묻는 질문

▾

How do I calculate hours worked across multiple days?

Sum each day: (end−start)−unpaid breaks. Convert to decimal (30 min = 0.5 hrs). Total = sum of all days.

Should I round punch times?

Depends on company policy. Some round to nearest 15 min. Best practice: track exact times for accuracy.

How do I handle overnight shifts (after midnight)?

Add 24 hours to end time if it's the next day. 11pm to 7am = 11:00 to 31:00 = 20 hours work.
