## Basics of Date Related Functions

It will be fun for you when you get used to several Excel functions. Same as date or time-related functions.

- There is a function called
**the TODAY function**. This function returns the current date If you just write**TODAY()**and then hit**Enter**you will get the date of the current day. - Another function I prefer mentioning here is
**the NOW function**. This function returns the current date and time with formatting. If you write**NOW()**and then press**Enter**then the function will return the current date and time.

## 5 Easy Methods to Calculate Age on a Specific Date with Formula in Excel

Before diving into the bigger picture, let’s get to know about today’s practice workbook. There are **3** columns, **Name**, **Date of Birth**, and **Specific Date**. Using the data in this table we will **calculate** **the age on a specific date**. I will show you how to **calculate age on a specific date** using Excel formula in 5 different ways.

### 1. Use Generic Formula with INT Function to Get Age on a Specific Date

To calculate age you simply need to get the difference between two dates **(Date of Birth and Calculating Date)**. Since age is calculated on a yearly basis, you will need to divide the difference by **365**.

So, the formula will be like this,

**(Calculating Date – Date of Birth) / 365**

But this may give us value in fractions. We don’t want age as a fraction value (unless any rear case). So while writing in Excel we will calculate this within **the INT function**. So the formula will be,

**INT((Calculating Date – Date of Birth) / 365))**

Let’s see how to **calculate age on a specific date **using the generic formula in Excel.

**Steps:**

- In the beginning, select the cell where you want to calculate the
**Age**. here, I selected cell**E5**. - Then, in cell
**E5**write the following formula.

`=INT((D5-C5)/365)`

- After that, press
**Enter**to get the**Age**.

**🔎** **How Does the Formula Work?**

**(D5-C5)/365:**Here, the value in cell**C5**is**subtracted**from the value in cell**D5**. And then, the result is**divid**ed by**365.****INT((D5-C5)/365):**Now, the**INT**function returns the integer portion of the decimal number.

- Next, drag the
**Fill Handle**down to copy the formula.

- Finally, you can see that I have copied the formula to the other cells.

### 2. Employ IF Function to Calculate Age on a Specific Date in Excel

If there is a situation where anyone inserts a date older than the **Date of Birth**, what will happen then? To nullify that kind of situation you can use **the IF function**. Let’s see the steps.

**Steps:**

- Firstly, select the cell where you want to calculate
**Age**. - Secondly, write the following formula in that selected cell.

`=IF(D5>C5,INT((D5-C5)/365),"Not Born")`

- Thirdly, press
**Enter**and you will get the**Age**.

**🔎** **How Does the Formula Work?**

**(D5-C5)/365:**Here, the value in cell**C5**is**subtracted**from the value in cell**D5**. And then, the result is**divided**by**365**.**INT((D5-C5)/365):**Now, the**INT**function returns the integer portion of the decimal number.**IF(D5>C5,INT((D5-C5)/365),”Not Born”):**The**IF**function checks if the value in cell**D5**is**greater than**the value in cell**C5**. If the**logical_test**is**True**then the formula will return the**Age**. Otherwise, It will return**“Not Born”**.

- After that, drag the
**Fill Handle**down to copy the formula to the other cells.

- Lastly, in the following picture, you can see that I have copied the formula to all the other cells and got my desired output.

### 3. Age Calculation on a Specific Date with Excel YEARFRAC Function

You can calculate age using **the YEARFRAC function**. This function takes** three** parameters, **start_date**, **end_date,** and **basis**. The** basis** is the day count base. Like if you use** 0** it will count setting the base **360 **days in a year. If you use **3**, it will count on the base of **365** days in a year. Here, I will use** 3**.

Writing this function may give a fraction value. So, I will round this using** the ROUNDDOWN function**. This function takes **two **parameters. **First**, the value you want to round, and the **second** one is how many decimal points you want. Since I don’t want to see any decimal in the Age value, I will use **0**.

Let’s see how you can use the** YEARFRAC** function and the **ROUNDDOWN** function in Excel formula to **calculate age on a specific date**.

**Steps:**

- First, select the cell where you want to calculate the
**Age**. Here, I selected cell**E5**. - Next, in cell
**E5**write the following formula.

`=ROUNDDOWN(YEARFRAC(C5,D5,3),0)`

- Afterward, press
**Enter**.

**🔎** **How Does the Formula Work?**

**YEARFRAC(C5,D5,3):**Here, the**YEARFRAC**function returns a decimal value that represents the years between the date in cells**C5**and**D5**.**ROUNDDOWN(YEARFRAC(C5,D5,3),0):**Now, the**ROUNDDOWN**function round downs the decimal value to zero decimal point or you can say integer.

- Then, drag the
**Fill Handle**down to copy the formula to the other cells.

- Consequently, you can see that I have copied the formula to the other cells.

### 4. Employ Excel Formula with DATEDIF Function to Get Age on a Specific Date

You can get the age by using **the DATEDIF function**. This function has **three** parameters, **start_date**, **end_date**, and **format**. Let’s see how you can employ the **DATEDIF** function in the Excel formula to **calculate the age on a specific date**.

**Steps:**

- Firstly, select the cell where you want the
**Age**. Here, I selected cell**E5**. - Secondly, in cell
**E5**write the following formula.

`=DATEDIF(C5,D5,"Y")`

- Thirdly, press
**Enter**to get the result.

**DATEDIF**function, I selected cell

**C5**as

**start_date**,

**D5**as

**end_date**, and

**“Y”**as a

**unit**.

**“Y”**means the complete years during this period. The formula returns the years between these two dates.

- After that, drag the
**Fill Handle**to copy the formula to the other cells.

- Finally, you can see that I have copied the formula to the other cells.

### 5. Determine Age with Years, Months, and Days in Excel

Now, in some situations, you may need to present the **age** with **years**, **months**, and **days**. Let’s see how you can do that. I will use the **DATEDIF** function and the **Ampersand Operator (&) **for this calculation. The **Ampersand Operator (&)** is used for joining more than one function together. In the beginning, I will calculate the difference in year format, then in months, and then in days.

Let’s see how you can **calculate age with years, months, and days on a specific date** by using an Excel formula.

**Steps:**

- In the beginning, select the cell where you want to calculate the
**Age**. - Then, write the following formula in that selected cell.

`=DATEDIF(C5,D5,"Y")&"Y " & DATEDIF(C5,D5,"YM")&"M " &DATEDIF(C5,D5,"MD")&"D"`

- Next, press
**Enter**to get the**Age**.

**🔎** **How Does the Formula Work?**

**DATEDIF(C5,D5,”Y”):**Here, the**DATEDIF**function returns the years between the dates in cells**C5**and**D5**.**DATEDIF(C5,D5,”YM”):**Now, the**DATEDIF**function returns the number of months between the dates in cells**C5**and**D5**ignoring the days and years.**DATEDIF(C5,D5,”MD”):**Here, the**DATEDIF**function returns the number of days between the dates in cells**C5**and**D5**ignoring the months and years.**DATEDIF(C5,D5,”Y”)&”Y ” & DATEDIF(C5,D5,”YM”)&”M ” &DATEDIF(C5,D5,”MD”)&”D”:**Now, the**Ampersand Operator (&)**joins the formulas.

- Afterward, drag the
**Fill Handle**down to copy the formula to the other cells.

- In the end, you can see that I have copied the formula and got my desired output.
