### Understanding the Date Function

When dealing with dates in Excel, understanding the intricacies of the Date Function is crucial. This function enables users to manipulate and format dates to calculate age, time differences, or any other relevant information. It helps eliminate the chances of errors and adds precision to calculations.

To use the Date Function, one must understand its syntax. The Date Function requires at least three arguments in sequence: year, month, and day. This means that if a user needs to calculate someone’s age based on their date of birth against today’s date, they will have to extract all three arguments from both dates and subtract them using a formula.

Furthermore, it’s important to ensure that the cells containing dates are formatted correctly as dates instead of plain text or numbers. To do this, users have several options; they can either use keyboard shortcuts or Format Cells options from the Home tab.

Another useful function that can help in date-related calculations is TODAY(). This function returns today’s date automatically in whichever cell it is placed, enabling users to compare it with other dates without having to input it manually.

In summary, mastering basic functions such as DATE() and ensuring appropriately formatted cells can make age calculation in Excel a breeze. Finally, using automated functions such as TODAY() ensures precision in these calculations while reducing manual error chances.

Today’s date is always a reminder that deadlines are looming and procrastination is a dangerous game. Let’s master the Today function in Excel instead.

### Understanding the Today Function

Today Function is an Excel formula that calculates the current date on your computer. This function can come in handy when creating a spreadsheet to calculate ages. It ensures that the age calculation updates automatically every day, saving you time and effort to manually update it.

By using Today Function, we can subtract the birthdate from the current date to obtain the person’s age. For example, if cell A1 contains the person’s birthdate and cell B1 contains =Today (), we simply create another cell with the following formula: `=(B1-A1)/365.25`.

This enables us to display the age of a person in years with decimals for more accurate results. We can further customize this by rounding up or down depending on our preference.

Using Today Function also ensures that our age calculation remains accurate, regardless of changes made to the spreadsheet over time.

It is important to note that this function may recalculate itself each time we open or save our Excel file. Therefore, it might be best to use references instead of hardcoding dates into formulas.

In 1993, Microsoft introduced Today Function as part of their Office software package. It has been widely used since then and is an essential element for many Excel users when calculating dates and ages.

DATEDIF function: perfect for when you need to calculate your age, but don’t want to do the math yourself.

## Age Calculation from DATEDIF Function

### Syntax of DATEDIF Function

The DATEDIF function is a useful Excel formula that helps to calculate the difference between two dates. It can be used to determine age by calculating the number of years, months, and days between a birthdate and the current date.

1. Start the formula with ‘=DATEDIF(‘.
2. Type or select the start date cell reference (e.g., A2) followed by ‘,’.
3. Type or select the end date cell reference (e.g., TODAY()) followed by ‘,’.
4. Select ‘Y’ (for years), ‘M’ (for months), or ‘D’ (for days) for your result type followed by ‘,’.
5. Close the parentheses with ‘)’
6. Press enter to see your answer.

Keep in mind that the DATEDIF function may return unexpected results if either date is entered as text rather than as a valid Excel date. Also note that this function is not available in all versions of Excel.

Let’s be honest, the only time we want to calculate age is to feel better about our own aging process.

### Examples of DATEDIF Function

The DATEDIF function in Excel is exceptionally versatile and can be used to calculate different time intervals. One of the most popular applications of DATEDIF is calculating age. By using specified formats, you can derive a person’s age from their birthdate. It can also calculate the number of completed years between two dates.

To use DATEDIF for calculating age, you need to enter three arguments: the date of birth, the current date, and the format code “Y.” This format code accounts for leap years, so your calculation will always be accurate. You can also use other format codes like “M” to calculate months or “D” to calculate days.

Besides calculating age, the DATEDIF function can also determine the number of days between two dates or how long it’s been since a specific event occurred. It is an incredibly versatile function that simplifies complex calculations by breaking them down into easier-to-understand parts.

It’s fascinating to note that DATEDIF was designed for compatibility with Lotus 1-2-3–a spreadsheet program even older than Excel–and has been included in all modern versions of Excel ever since.

### Syntax of INT Function

INT Function Syntax – How to Write it Correctly

INT function is written as `=INT(number)`. It takes only one argument which is the number that you want to round down.

To round down a number to its nearest integer value or multiple of 10, use INT function with the specified number inside it. This can be helpful in a variety of scenarios like calculating age using birthdate.

For example, if you have a birthdate column in Excel, subtract it from today’s date and wrap it inside the INT function to get the age of the person. This will give you an integer value as the result.

One thing to keep in mind when using this function is that it always rounds down. So if you have a decimal value like 5.7, applying INT function on this will give you an output of 5.

It is good practice to use brackets while writing the formula and placing the number inside these brackets for effective calculations.

According to Microsoft Excel official documentation, INT function was first introduced in Excel version 1.0 in 1985.

Get ready to round down and calculate like a pro with these INT examples.

### Examples of INT Function

The INT Function is a powerful tool in Excel that can be used in various ways. Here’s how to harness its power to calculate age.

1. First, select the cell where you want the age calculation to appear.
2. Next, enter the formula: `=INT((TODAY()-B2)/365.25)`, wherein B2 refers to the birth date of the person.
3. Press Enter to see the calculated age in years.
4. To make it more presentable, apply the appropriate formatting.

The INT Function can also be used for rounding off numbers or truncating decimals, depending on your needs. This versatile function can simplify complex calculations and has become a staple tool in Excel users’ arsenal.

Fun fact: The INT Function was first introduced in Excel 1.0 way back in 1985 and has since evolved into one of the most commonly used functions in Microsoft Excel today. Aging gracefully is a myth, but calculating your age in Excel is as easy as pie with the YEARFRAC function.
