## DATEDIF: Excel Formulae Explained

Ever struggled with calculating the difference between two dates in Excel? Try the powerful DATEDIF function! In this section, we’ll dive into its structure and how it works. We’ll take a glance at the arguments that determine calculations. By the end, you’ll be able to leverage the DATEDIF function to solve date-related problems quickly and efficiently.

### Understanding the Basics of DATEDIF Function

DATEDIF function does not accept decimal places as part of its output. That means, if it calculates 1.5 years or 6.25 months, it rounds down to one year and six months respectively.

This formula has various time units, like “md” which stands for the number of days between two dates. Other indicators include “ym” for the number of whole months between two dates, and “yd” meaning the number of days left between two dates after the completed years are subtracted.

Before Excel added this formula in 2000 versions and moving forward, users had to use complicated workarounds with subtraction and division functions.

Microsoft confirmed that DATEDIF‘s manual formula was never meant for public use, yet users all over the world find it highly valuable.

Analyzing the Arguments of DATEDIF Function can help us better understand how this formula works by taking a close look at its inputs.

### A Quick Glance at DATEDIF Function’s Arguments

A quick look at DATEDIF Function’s Arguments shows us the parameters used. Let’s check out the table:

Argument Explanation
Start_date Date to start counting from
End_date Date to count up to
Unit Unit of time to calculate difference between dates

So, the three arguments are start date, end date and unit. Here are some useful tips on using them effectively.

For calculating days between two dates, set ‘start_date’ as the earlier one and ‘end_date’ as the later one. Plus, select ‘d’ as the unit. For months, use ‘m’, and for years, use ‘y’.

Also, ensure to enter all Excel dates using /, – or . This helps your formula get consistent input values, giving accurate results.

## Limitations of DATEDIF and How to Handle Them

Excel is awesome for crunching numbers and calculations. A helpful tool within it is the DATEDIF function. It helps you measure the difference between two dates in years, days, or seconds. Though useful, it has some restrictions. Here I’ll talk about these boundaries and how to manage them so you can get the best results from DATEDIF.

### Understanding the Limits of DATEDIF Function

The DATEDIF function is great for calculating time differences between two dates in Excel. But, there are some restrictions you should be aware of.

• You can only use three arguments with DATEDIF: start_date, end_date and unit.
• The start_date must be earlier or equal to the end_date.
• Plus, the unit argument must contain a valid value, such as “d” for days, “m” for months or “y” for years.
• Also, note that DATEDIF cannot calculate time differences greater than 7 days if you use the “d” unit argument. So, you may need to use additional functions or tools.
• There may be issues with DATEDIF when calculating time differences based on a specific day of the month. In this case, you could use DATEVALUE or EDATE.
• Leap years are also tricky, as DATEDIF interprets them as normal years when calculating days between two dates. If you need precise results, you should use NETWORKDAYS or WEEKDAY.
• Microsoft’s official documentation even states that “The result can appear incorrect when you apply formatting to display hours over 24.”

And to end on a fun note, did you know that the name “DATEDIF” stands for “Date Difference”?

Finally, here are some tips on how to get better use out of the DATEDIF function, despite its limitations.

### Tips to Overcome DATEDIF Function’s Limitations

The DATEDIF function in Excel has limitations. To tackle them, try some helpful tips.

1. Use other functions instead of DATEDIF. YEARFRAC, for instance, can calculate the fractional number of years between two dates with no limits.
2. If you want to calculate days beyond one year, use INT and MOD. These can break down the date difference into smaller segments and then add them up.
3. If your dates exceed Excel’s range limits, convert them to a decimal format. Do this by dividing the days from January 1st, 1900 by the total days in a day or year.
4. Get an add-in or plug-in that extends your Excel functionalities. This way, you’ll have advanced features for managing data and overcoming Excel’s limitations.

Last but not least, learn how each formula works before using it. Investing time in understanding functions like DATEDIF, their limitations, and workarounds will help in making better decisions with data.
