The document provides code snippets for calculating age in PHP, Python, Ruby, and Java. Each programming language has a specific method to determine age based on a given birthdate, handling cases such as leap years. Additionally, it references a website that utilizes these algorithms for live age calculation.

1. How to calculate your age
Php,Java,python,ruby ways.

2. PHP Ways
Function getMyAge($bithdayDate)
{
$date = new DateTime($bithdayDate);
$now = new DateTime();
$interval = $now->diff($date);
return $interval->y;
}

3. Python ways
from datetime import date
def calculate_age(born):
today = date.today()
try:
birthday = born.replace(year=today.year)
except ValueError: # raised when birth date is February 29 and the current year is not a leap year
birthday = born.replace(year=today.year, month=born.month+1, day=1)
if birthday > today:
return today.year - born.year - 1
else:
return today.year - born.year

4. Ruby & Rails Way
• from datetime import date
• def calculate_age(born):
• today = date.today()
• try:
• birthday = born.replace(year=today.year)
• except ValueError: # raised when birth date is February 29 and the current year is not a leap
year
• birthday = born.replace(year=today.year, month=born.month+1, day=1)
• if birthday > today:
• return today.year - born.year - 1
• else:
• return today.year - born.year

5. Java ways
LocalDate birthdate = new LocalDate (1970, 1, 20);
LocalDate now = new LocalDate();
Years age = Years.yearsBetween(birthdate, now);

6. Live Website Using those algorithm
