## How to use DATEDIF

Do you want to use the DATEDIF function? Knowing the Syntax and Arguments of the DATEDIF function is required. With this knowledge, you can calculate various things involving dates. For example, finding a person’s age or the duration between two events.

### Syntax of DATEDIF function

The DATEDIF function has a complex syntax that requires proper understanding to utilize. It is formulated as `DATEDIF(start_date, end_date, unit)`, where start date and end date refer to the two dates that need to be compared, and unit refers to the desired type of result. The function calculates the difference between two dates in years, months or days depending on the selected “unit”.

To use this formula effectively, it is crucial to select the appropriate “unit” parameter to obtain the required output. For instance, if one desires to know the number of months between two dates, one can use “M” for “unit”. Once this function is applied with suitable parameters, we get accurate calculations.

It’s important to note that DATEDIF function belongs to a category of nondocumented functions in Excel. Due to this reason, it often goes unnoticed by beginners and even some experts too. However, by utilizing DATEDIF adequately and appropriately can save users substantial time when dealing with commercial or financial data.

In history, although Excel was developed in 1985; DATEDIFF was included only after the release of Excel 2000 edition as Microsoft removed it from future updates due to some internal software criteria but still managed to keep it alive behind doors in its vivid world of functions until today’s edition. Excel users always felt logical inconsistencies due to the absence of such essential tools before up-gradation from DOS platform. And since then, it proved an efficient mechanism for programming new Events & Functions which further benefitted many professionals coming from Finance& IT background.

Looking for an argument? Just try using the DATEDIF function with Excel, guaranteed to stir up a debate among even the most mild-mannered spreadsheet enthusiasts.

### Arguments of DATEDIF function

The DATEDIF function in Excel is used to calculate the difference between two dates in years, months or days. The arguments of this function include the start date, end date and a unit specifier that denotes the type of interval to be calculated.

To use this function, the first argument should be entered in cell A1, the second argument in cell B1 and finally, the unit specifying argument in quotation marks (“d” for days, “m” for months or “y” for years) within parentheses.

It’s important to note that this function has some limitations, such as not being supported by newer versions of Excel and producing errors when negative date values are used.

If you encounter any issues while using this function, it’s advised to seek help from an expert or utilize other methods available such as custom functions or VBA code.

As an example of how this function can be utilized, consider a case where someone needs to know their age based on their birth date. By using the formula “=DATEDIF(A1,TODAY(),”y”)”, they can calculate their current age in years accurately.

A friend once struggled with calculating the duration of a project which lasted several months; fortunately, she discovered the DATEDIF function that made her job significantly easier.

Get your dates straight with DATEDIF, because life is confusing enough without mixing up your months and days.

## Examples of DATEDIF function usage

Need to find the difference between two dates in Excel? Use the DATEDIF function! We’ll explore different ways to use it for working with dates. Examples include calculating days, months, and years between two dates. With DATEDIF, it’s easy to get the answer you’re looking for.

### Calculating the number of days between two dates

To compute the duration of days between two dates using Excel spreadsheets, you can use DATEDIF function, which is a handy tool. Here’s how to use it.

1. Select an empty cell, and in the formula bar type `DATEDIF("` without quotes.
2. Next, in quotation marks “`dd/mm/yyyy`” format or click on the cell containing the first date, then add a comma.
3. In another quotation mark following this pattern again “`dd/mm/yyyy`” format or click on the cell containing the second date followed by a comma again.
4. At last, put in another quotation mark and include “`d`” for counting days between these particular dates; follow the semicolon with `0` or eliminate this component entirely to obtain results that lack decimal points.

To calculate the duration of days between two dates excel has another great formula known as DATEDIF. This function is very flexible and helpful than manually taking out dates separately from various cells.

The utilization of this method reduces manual effort and saves time analytical errors that often hamper productivity. It can be particularly useful for those whose work explicitly entails figuring out what interval exists between different static periods within spreadsheets.

Consider using templates with pre-built formulas for ease and accuracy with complex calculations involving numerous cells and references per sheet created depending on requirements while minimizing errors via formulae-based analysis rather than relying solely on static values that could fluctuate over time or lack relevance to specific analytics goals.

Counting the months and years between two dates is like trying to calculate your age after a night of heavy drinking – it’s always a little fuzzy.

### Calculating the number of months or years between two dates

## Limitations of DATEDIF function

The shortcomings of the DATEDIF function can be a hindrance while using it for complex calculations. Here are five limitations of the DATEDIF function to keep in mind:

• It cannot handle negative date differences which may lead to inaccurate results.
• The function is not available in the pre-2007 versions of Excel, so it may limit compatibility with older versions.
• The function can incorrectly interpret the day count for entire months, leading to incorrect results in some cases.
• The DATEDIF function does not distinguish between leap years and regular years when calculating the year difference.
• It does not support decimal calculations, which may lead to reduced accuracy in some scenarios.

It is essential to keep these limitations in mind while working with the DATEDIF function. It is worth exploring alternative functions with more advanced capabilities to ensure accurate results.

A unique detail to note is that while the DATEDIF function’s name suggests it calculates date differences, it can also calculate the year, month, and day for a given date range, making it a versatile function.

Pro Tip: Instead of using DATEDIF, consider using the more robust and versatile DATE function, which can accommodate more complex calculations and does not suffer from DATEDIF’s limitations.
