What if you only counted weekdays?

In some cases, you might want to skip weekends and count only the weekdays. This could be useful if you know you have a deadline based on a certain number of business days. If you are trying to see what day falls on the exact date difference of 1 weekday before Jan 28, 2025, you can count up each day skipping Saturdays and Sundays.

Start your calculation with Jan 28, 2025, which falls on a Tuesday. Counting forward, the next day would be a Wednesday.

To get exactly one hundred weekdays before Jan 28, 2025, you actually need to count 2 total days (including weekend days). That means that 1 weekday before Jan 28, 2025 would be January 26, 2025.

If you're counting business days, don't forget to adjust this date for any holidays.
