Lets get to it

DAYS Formula

The DAYS formula calculates the number of days between two dates. Its structure is straightforward:

=DAYS(end_date, start_date)

Here, "start_date" represents the earlier date, and "end_date" represents the later date. The formula will give you the exact number of days between the two dates.

DATEDIF Formula

The DATEDIF formula is perfect for calculating the difference between two dates in days, months, or years. To use it, follow this syntax:

=DATEDIF(start_date, end_date, "d")

Simply replace "start_date" and "end_date" with the cell references or date values representing the start and end dates. The "d" in the formula specifies that you want the difference in days.

WORKDAY Formula

The WORKDAY formula is similar to NETWORKDAYS but allows you to exclude a list of holidays from the calculation. The syntax is as follows:

=WORKDAY(start_date, days, holidays)

Here, "start_date" represents the initial date, "days" is the number of working days to add, and "holidays" should be a range of cells containing holiday dates.

NETWORKDAYS Formula

If you need to count the number of working days (excluding weekends) between two dates, the NETWORKDAYS formula is what you need:

=NETWORKDAYS(start_date, end_date)

Again, replace "start_date" and "end_date" with the cell references or date values. This formula automatically excludes weekends (Saturday and Sunday) from the count.

TODAY Formula

The TODAY formula is a simple yet handy one that returns the current date. It requires no arguments and works like this:

=TODAY()

This formula will always display today's date whenever you open or recalculate the Excel sheet.

To ensure the formulas output the numerical value of the days, remember to format the cells displaying the results as "General" or "Number."

Excel offers a wide range of date and time functions that can be combined to perform even more complex date calculations. By mastering these basic formulas, you'll be well on your way to becoming an Excel pro when it comes to working with dates! Happy counting!
