This formula takes advantage of the fact that dates are just sequential numbers in Excel. It determines the last day of the previous year and subtracts that value from the original date with this formula:
The result is nth day of the year, based on the date in cell B5. Notice the day argument in the DATE function is supplied as zero. A nice feature of DATE is it can handle day values that are "out of range" and adjust the result appropriately. When we give DATE a year for year, a 1 for month, and a zero for day, the DATE function returns the last day of the previous year:
The goal in this example is to return the amount of time completed in a year as a percentage value, based on any given date. In other words, when given the date July 1, 2021, the formula should return 50% since we are halfway* through the year. *By...
The Excel DATE function creates a valid date from individual year, month, and day components. The DATE function is useful for assembling dates that need to change dynamically based on other values in a worksheet.
The Excel YEAR function returns the year component of a date as a 4-digit number. You can use the YEAR function to extract a year number from a date into a cell or to extract and feed a year value into another formula, like the...
