7 Excel Formulas To Find The First Day Of Any Month

Finding the first day of any month in Excel can seem daunting, especially with so many formulas to choose from. But fear not! We're here to simplify it for you. In this article, we'll explore seven effective Excel formulas that will help you easily find the first day of any month. Along the way, we'll share tips, common mistakes to avoid, and troubleshooting techniques. Let's jump right in! 📅

1. Using the DATE Function

The DATE function is a straightforward way to find the first day of any given month. The syntax is simple: DATE(year, month, day). Here’s how you can do it:

=DATE(YEAR(A1), MONTH(A1), 1)

• Explanation: This formula retrieves the year and month from cell A1 and sets the day to 1, thus returning the first day of that month.

2. Leveraging the EOMONTH Function

The EOMONTH function finds the end of the month, but we can modify it to find the first day too. The syntax is: EOMONTH(start_date, months).

=EOMONTH(A1, -1) + 1

• Explanation: This formula finds the last day of the previous month (using -1) and then adds 1 to get the first day of the current month.

3. Combining TEXT with DATE

If you're working with textual representations of months, you can combine TEXT with DATE to achieve your goal. Here’s how:

=DATE(YEAR(A1), MONTH(A1), 1)

• Explanation: Similar to the first example, this uses the year and month from A1 to return the first day of that month.

4. Using the CONCATENATE Function

For those who like a twist, you can use CONCATENATE to create a string that Excel can convert into a date.

=DATE(VALUE(LEFT(A1, 4)), VALUE(MID(A1, 6, 2)), 1)

• Explanation: If A1 has a date in the format "YYYY-MM-DD", this formula extracts the year and month, setting the day to 1.

5. The First Day of Month from Current Date

If you want the first day of the month based on today's date, you can use:

=DATE(YEAR(TODAY()), MONTH(TODAY()), 1)

• Explanation: This formula retrieves the current year and month using TODAY() and returns the first day of the current month.

6. Using 1st January as Base Date

If you are focusing on a specific year, you can simplify the formula even more:

=DATE(2023, A1, 1)

• Explanation: If A1 holds the month number (1 for January, 2 for February, etc.), this will return the first day of that month in the year 2023.

7. Array Formula for Multiple Months

If you need to find the first days for multiple months at once, using an array formula can be handy:

=ARRAYFORMULA(DATE(YEAR(A1), ROW(A1:A12), 1))

• Explanation: This formula generates the first days for each month of the year based on the year from cell A1.

Common Mistakes to Avoid

1. Using the Wrong Cell Reference: Always ensure you're referencing the correct cell that contains your date.
2. Formatting Issues: If your output appears as a number instead of a date, check your cell formatting and set it to 'Date'.
3. Forgetting the DAY Parameter: Some formulas can omit the day parameter, which is crucial for getting the first day.

Troubleshooting Issues

• Issue: The result is not showing as a date.

  • Solution: Right-click on the cell, choose Format Cells, and select Date.

• Issue: You're getting an error message.

  • Solution: Double-check that your input cells (like A1) contain valid dates.
