Count number of people across multiple columns with criteria
问题 I have a worksheet that has 6 columns for each employee and family members birthdays. I am looking to get the total number of kids that are 20 years old and younger without adding any additional columns based on the date in cell B1. I looked into using COUNTIF, but it needs a range to execute. Here is how my workbook looks: I am looking for one formula that takes all birthdays from columns C-F and counts how many children are younger than 20 years old. Is this possible? Answers I am seeking
