- date—The date from which you want to return the day as a number
For leap years, YEARDAY returns a number between 1–366.
This example references the following sheet information:
|Clothing Item||Units Sold||Sold Date||Order Date||Ship Date|
|1||T-Shirt||78||02/12/19 1:55 PM||02/12/19||02/15/19|
|2||Pants||42||02/15/19 10:23 AM||02/15/19||03/20/19|
|3||Jacket||217||02/20/19 2:45 PM||02/20/19||02/27/19|
Given the table above, here are some examples of using YEARDAY in a sheet:
|=YEARDAY([Ship Date]1)||Returns the number of days in to the year for the date from row 1 of the Ship Date column||46|
|=IF(YEARDAY([Ship Date]2) < 182, "First Half of Year", "Second Half of Year")||Returns the string First Half of Year if the number of days in to the year for the date from row 2 of the Ship Date column is less than 182. Otherwise, the function returns Second Half of Year.||First Half of Year|
|=ROUND([Units Sold]3 / YEARDAY([Order Date]3), 2) + “Avg jackets units sold each day”||Divides the value in row 3 of the Units Sold column by the number of days in to the year for row 2 of the Ship Date column, returns the rounded result, and adds the string Avg Jacket units sold each day (with a space and period) to the end||4.25 Avg Jacket units sold each day.|
