Frequently Asked Questions
How are business days calculated?
Business days exclude weekends (Saturday and Sunday). Our calculator estimates by multiplying total days by 5/7. For exact counts excluding holidays, adjust manually.
Does this account for leap years?
Yes. The calculator uses actual calendar dates, so leap years are automatically included in the calculation.
How many days are in a year?
A common year has 365 days, while a leap year has 366. The average is 365.25 days per year, which we use for the years calculation.
