# How to Find First Day of the Month in Excel: Step-by-Step

All Excel functions are useful in many different ways.

You can look up, calculate values, and a whole lot more.

And by more, you can also** find the first day of the month in Excel.**

There is no direct function for determining the first date of the month based on a specified date. But with a formula, it’s possible in Excel 😉

Learn exactly how to find the first day of the month in this Excel tutorial 👍

## Excel formula for the first day of the month

You have to find the first day of the given dates in the example below.

You can use a formula to find the beginning date of the month 🥳

Let’s learn a simple formula to find the start date of a month 📆

- Enter an equal sign and select the EOMONTH function.

The EOMONTH function helps to get the last day of a month after adding or deducting a specified number of the month.

**=EOMONTH(**

- Select the given date as the start date.

In this example, you have to select cell A2.

So, your updated EOMONTH formula is;

**=EOMONTH(A2**

- Enter minus 1 (-1) as the second argument of the EOMONTH function and close the parenthesis. By entering -1, you can get the last date of the previous month.

So, your updated EOMONTH formula is;

**=EOMONTH(A2,-1)**

You have now finished the first part of the formula. So now you have got the last day of the previous month.

- The second part is to add a one to the date of the first part. Then you can get the first day of the current month.

After adding 1, the formula bar should show the following formula.

**=EOMONTH(A2,-1)+1**

You can apply the same formula for other dates as well.

If the result of the formula is a serial number of the date value, you have to change the cell format to “Date”.

In summary, this formula works like this. First, we find the last day of the previous month of the original date.

Then, we add one day to get the first day of the current month.

**Pro Tip!**

You can also use the DAY function to get the first day of the month on a given date 🤩

The DAY function returns the day value or day number of a specified date.

In order to get the answer, subtract the outcome of the DAY function from the original date and then add 1.

**=A2-DAY(A2)+1**

The EOMONTH formula and this formula both perform in the same way.

To determine the beginning day of the current month, first, get the end date of the previous month and then add one.

## That’s it – Now what?

Nice work! 👍

Getting the first day of the month might be a simple thing to do and you might think that you don’t need an Excel formula for it.

But now you learned that it can be done in Excel, among other amazing things.
