FAQs

Q: How can I determine someone’s age in years, months, and days? A: To determine a person’s age in years, months, and days, follow these steps: Subtract the birth date from the current date to find the differences in years, months, and days. Use the formula: age = (years × 365) + (months × 31) + days. Then, divide the total by the number of years obtained in the first step, rounding down to the nearest whole number for the age in years.

Q: What is the process for calculating my precise age? A: To calculate your exact age, first determine the number of complete years by subtracting your birth year from the current year. Then, find the number of full months by subtracting your birth month from the current month. This will give you your age in years and months.

Q: How is the aging date for accounts receivable (AR) determined? A: The aging date for accounts receivable is calculated by considering the payment terms of a customer invoice and the date when the aging report is created. The age of an invoice is the time that has passed from its due date to the date of the report.

Q: What method can I use to calculate my exact age in years, months, and days using Excel? A: In Excel, to calculate age on a specific date, enter the formula =DATEDIF(A2, B2, “Y”) to get the age in years as of a specific date. For a detailed age in years, months, and days, use the formula =DATEDIF(A2, B2, “Y”) & ” Years, ” & DATEDIF(A2, B2, “YM”) & ” Months, ” & DATEDIF(A2, B2, “MD”) & ” Days”. Replace A2 with the cell containing the birth date and B2 with the cell containing the specific date you’re measuring from.
