In a year, there are 365 days. Since a week consists of seven days, a year can be divided into 52 weeks and 1 day. So, the number of weekdays in a year is:
52 weeks * 5 weekdays/week = 260 weekdays
Leap Years
Every four years, we have a leap year with an extra day added to the month of February. This means that in a leap year, there are 366 days. Therefore, the number of weekdays in a leap year is:
52 weeks * 5 weekdays/week + 1 day = 261 weekdays
