DATEDIF function

PRO

The DATEDIF function in Jspreadsheet Formulas Pro is used to calculate the difference between two dates based on a specified interval. This could be in terms of days, months, or years. You provide two dates, the start date and the end date, and the interval type, and the function will return the difference according to your chosen interval. This is particularly useful when you need to find out the duration between two specific dates.

Documentation

Calculates the difference between two dates based on the specified interval.

Syntax

DATEDIF(start_date, end_date, interval)

Parameter	Description
`start_date`	The start date of the time period.
`end_date`	The end date of the time period.
`interval`	The type of time unit to use for the calculation: "Y" for full years, "M" for full months, and "D" for full days. "MD" returns the number of days between two dates, ignoring months and years. "YM" returns the number of months between two dates, ignoring years. "YD" returns the number of days between two dates, ignoring the year component.

Behavior

The DATEDIF function calculates the number of days, months, or years between two dates. Here is how it handles various inputs:

Empty cells: If either or both of the date cells are empty, DATEDIF returns a #VALUE! error due to invalid or missing inputs.
Text: If a cell contains text instead of a date, DATEDIF returns a #VALUE! error since it only works with date values.
Booleans: Boolean values are not valid inputs for DATEDIF. If a cell contains a boolean value, the function returns a #VALUE! error.
Errors: If a cell referenced in the DATEDIF computation contains an error, the function propagates that error.
Dates: It expects the start date to be less than or equal to the end date. If the start date is greater than the end date, DATEDIF returns a #NUM! error.
Units: The unit parameter in DATEDIF should be a text value either "Y" for years, "M" for months, "D" for days, "YM" for months excluding years, "YD" for days excluding years, or "MD" for days excluding years and months. Any other value will result in a #VALUE! error. The unit parameter is case-sensitive and must be provided as a uppercase string (e.g., "Y", not "y").

Common Errors

Error	Description
`#VALUE!`	This error is returned when the start date, end date, or both are not valid dates (e.g., empty cells, text, boolean values, etc.). It also occurs if an invalid unit is provided.
`#NUM!`	This error occurs when the start date is greater than the end date.

Best practices

Always ensure that your start date is less than or equal to your end date to avoid a #NUM! error.

Only use valid date formats that your spreadsheet software recognizes. Inconsistent or incorrect date formats can lead to errors or incorrect results.

Be aware that DATEDIF ignores time values in dates. If you need to account for time, consider using a different function or calculation.

Ensure the unit parameter is correctly specified as either "Y", "M", "D", "YM", "YD", or "MD". Other values will result in a #VALUE! error.

Usage

A few examples using the DATEDIF function.

DATEDIF("2022-01-01", "2022-03-15", "D")  →  Returns 73
DATEDIF("2020-06-01", "2022-06-01", "Y")  →  Returns 2
DATEDIF("2020-01-01", "2022-06-01", "YM") →  Returns 5
DATEDIF("2020-01-01", "2022-06-01", "YD") →  Returns 151
