YEAR function

PRO BASIC

The YEAR function in Jspreadsheet Formulas Pro is a useful tool when working with dates. It allows you to extract the year from a specified date. By inputting a date into the YEAR function, it will return the year of that date as a four-digit number. This can be particularly useful when analyzing data that spans over multiple years.

Documentation

Returns the year corresponding to a given date.

Syntax

YEAR(date)

Parameter	Description
`date`	The date for which to extract the year.

Behavior

The YEAR function returns the year of a specific date as a four digit number. Here's how it handles different types of input:

Date: The function works best with valid date values and returns the year part of the date as a four-digit number. For example, if the date is '2022-05-14', YEAR will return 2022.
Empty Cells: If the YEAR function is applied to an empty cell, it will typically return an error because it expects a date value as input.
Text: If a cell containing text (which doesn't represent a date) is used as an input, the YEAR function will usually return an error.
Booleans: The YEAR function generally treats Boolean values as errors since it expects a date input.
Errors: If the reference cell contains an error, the YEAR function will also return an error.

Common Errors

Error	Description
#VALUE!	This error is returned when the input argument to the `YEAR` function is not a valid date. This can occur if the input is an empty cell, a cell containing text, or a Boolean value.
#NUM!	This error is returned if the date value is invalid or outside Jspreadsheet’s supported range.

Best practices

Always ensure that the input to the YEAR function is a valid date. If there's a chance that the input cell might not contain a date, consider using error-handling functions to manage potential errors.

When importing data, ensure that dates are imported in a format that your spreadsheet program recognizes. If necessary, you can use date parsing functions to convert text to dates.

Be aware of the date range limitations of your spreadsheet program. If you're working with historical or future dates, ensure they fall within the acceptable range.

Use the YEAR function in conjunction with other date functions for more complex date manipulations. For example, you can use YEAR along with 'MONTH' and 'DAY' to construct new dates.

Usage

A few examples using the YEAR function.

YEAR("2022-03-15") returns: 2022  
YEAR("1995-12-31") returns: 1995  
YEAR("2000-01-01") returns: 2000
