Thursday, May 18th 2023. | Excel Templates Excel Formula to Count Days from Date to Today (8 Effective Ways) from www.exceldemy.com

## Introduction

Excel is a widely used tool for data analysis, and it offers a variety of functions to manipulate data. One of the most useful functions in Excel is the ability to calculate the number of days between two dates. Whether you need to calculate the number of days between two events or determine the duration of a project, Excel has got you covered.

## Sample: Count Days Between Dates Excel

Here are three examples of how to count days between dates in Excel:

### Example 1: Simple Calculation

To calculate the number of days between two dates, subtract the earlier date from the later date. For example, if you want to calculate the number of days between January 1, 2023, and January 15, 2023, you would enter the following formula in a cell:

=15-1

This will return the value 14, which means there are 14 days between the two dates.

### Example 2: Using the DATEDIF Function

Excel also has a built-in function called DATEDIF, which stands for “date difference”. This function allows you to calculate the number of days, months, or years between two dates. To use this function, enter the following formula in a cell:

=DATEDIF(start_date, end_date, “unit”)

Replace start_date and end_date with the cell references of the two dates you want to calculate the difference between. Replace “unit” with the unit you want to calculate (d for days, m for months, or y for years). For example, if you want to calculate the number of days between January 1, 2023, and January 15, 2023, you would enter the following formula:

=DATEDIF(A1, A2, “d”)

Assuming A1 contains January 1, 2023, and A2 contains January 15, 2023, this formula will return the value 14.

### Example 3: Using the NETWORKDAYS Function

If you need to calculate the number of working days between two dates (excluding weekends and holidays), you can use the NETWORKDAYS function. To use this function, enter the following formula in a cell:

=NETWORKDAYS(start_date, end_date, [holidays])

Replace start_date and end_date with the cell references of the two dates you want to calculate the difference between. If you have any holidays that fall within the date range, you can include them in the formula by listing them in a separate range of cells and referencing that range in the formula. For example, if you want to calculate the number of working days between January 1, 2023, and January 15, 2023, assuming New Year’s Day (January 1) and Martin Luther King Jr. Day (January 16) are holidays, you would enter the following formula:

=NETWORKDAYS(A1, A2, B1:B2)

Assuming A1 contains January 1, 2023, A2 contains January 15, 2023, B1 contains January 1, 2023, and B2 contains January 16, 2023, this formula will return the value 10.

## Tips for Counting Days Between Dates in Excel

Here are some tips to help you get the most out of Excel’s date functions: – Make sure your dates are in the correct format. Dates in Excel should be entered as four-digit years, followed by a hyphen, followed by two-digit months and two-digit days. For example, January 1, 2023, should be entered as 2023-01-01. – Use cell references instead of hardcoding dates in your formulas. This will make your formulas more flexible and easier to update if your dates change. – Be aware of leap years. Leap years occur every four years and can affect the number of days between two dates. You can use the YEAR function to determine if a year is a leap year, and adjust your formulas accordingly. – Use the TEXT function to format your dates. The TEXT function allows you to display dates in a variety of formats, such as “January 1, 2023” or “1/1/23”.

## Frequently Asked Questions (FAQ) about Counting Days Between Dates in Excel

### Q1. How do I subtract one date from another in Excel?

A1. To subtract one date from another in Excel, simply subtract the earlier date from the later date. For example, if you want to calculate the number of days between January 1, 2023, and January 15, 2023, you would enter the following formula in a cell:

=15-1

This will return the value 14.

### Q2. How do I calculate the number of days, months, or years between two dates in Excel?

A2. Excel has a built-in function called DATEDIF, which allows you to calculate the number of days, months, or years between two dates. To use this function, enter the following formula in a cell:

=DATEDIF(start_date, end_date, “unit”)

Replace start_date and end_date with the cell references of the two dates you want to calculate the difference between. Replace “unit” with the unit you want to calculate (d for days, m for months, or y for years).

### Q3. How do I calculate the number of working days between two dates in Excel?

A3. To calculate the number of working days between two dates (excluding weekends and holidays), you can use the NETWORKDAYS function. To use this function, enter the following formula in a cell:

=NETWORKDAYS(start_date, end_date, [holidays])

Replace start_date and end_date with the cell references of the two dates you want to calculate the difference between. If you have any holidays that fall within the date range, you can include them in the formula by listing them in a separate range of cells and referencing that range in the formula.

### Q4. Can I calculate the number of hours or minutes between two dates in Excel?

A4. Yes, you can use the HOUR and MINUTE functions to extract the hours and minutes from a date and time value, and then subtract them to calculate the difference. For example, if you have a start date and time in cell A1 and an end date and time in cell A2, you could calculate the number of hours between them with the following formula:

=(A2-A1)*24

This formula subtracts the start date and time from the end date and time, and then multiplies the result by 24 to convert it to hours.

### Q5. How do I calculate the number of days between two dates excluding weekends?

A5. To calculate the number of days between two dates excluding weekends, you can use the NETWORKDAYS function. This function automatically excludes weekends from the calculation. For example, if you want to calculate the number of days between January 1, 2023, and January 15, 2023, excluding weekends, you would enter the following formula:

=NETWORKDAYS(A1, A2)

Assuming A1 contains January 1, 2023, and A2 contains January 15, 2023, this formula will return the value 10.

### Q6. How do I calculate the number of days between two dates excluding holidays?

A6. To calculate the number of days between two dates excluding holidays, you can use the NETWORKDAYS function and specify a range of cells that contains the holiday dates. For example, if you want to calculate the number of days between January 1, 2023, and January 15, 2023, excluding New Year’s Day (January 1), you would enter the following formula:

=NETWORKDAYS(A1, A2, B1)

Assuming A1 contains January 1, 2023, A2 contains January 15, 2023, and B1 contains January 1, 2023, this formula will return the value 13.

### Q7. How do I format dates in Excel?

A7. You can use the TEXT function to format dates in Excel. The syntax of the TEXT function is:

=TEXT(value, format_text)

Replace value with the cell reference of the date you want to format, and replace format_text with the format you want to use. For example, to display a date in the format “January 1, 2023”, you would enter the following formula:

=TEXT(A1, “mmmm d, yyyy”)

Assuming A1 contains January 1, 2023, this formula will return the text “January 1, 2023”.
