This tool calculates your exact age from the day you were born.
How to Use the Birthday Calculator
To use this birthday calculator, enter the birthdate in the Day, Month, and Year fields and then click on the “Calculate” button. The results will display how many years, months, weeks, and days have passed since the given birthdate.
How It Calculates the Results
The birthday calculator works by taking the input birthdate and comparing it with the current date. It calculates the number of years, months, weeks, and days between these two dates:
- Years: The difference in calendar years between the current date and the input birthdate.
- Months: The difference in calendar months, adjusted to remove any overcount due to the difference in day numbers.
- Weeks: The number of weeks taken from the remaining days, calculated by dividing by 7.
- Days: The remainder of days after computing the weeks.
Limitations
The calculator uses a rough approximation of 30 days per month which might cause slight inaccuracies. The accuracy might also be impacted by variations in leap years and different days in months.
