- Calculate a person's age and the time remaining to their next birthday in years, months and days.
- Calculate differences between two dates in years, months and days.
- Add years, months and days to any date.

### Example

```
import 'package:age_calculator/age_calculator.dart';
void main() {
DateTime birthday = DateTime(1997, 3, 5);
DateDuration duration;
// Find out your age as of today's date 2021-03-08
duration = AgeCalculator.age(birthday);
print('Your age is $duration'); // Your age is Years: 24, Months: 0, Days: 3
//Find out your age on any given date
duration = AgeCalculator.age(birthday, today: DateTime(2030, 5, 1));
print('Your age is $duration'); // Your age is Years: 33, Months: 1, Days: 26
// Find out when your next birthday will be at 2021-03-08
duration = AgeCalculator.timeToNextBirthday(birthday);
print('You next birthday will be in $duration');
// You next birthday will be in Years: 0, Months: 11, Days: 25
// Find out when your next birthday will be on any given date
duration = AgeCalculator.timeToNextBirthday(birthday,
fromDate: DateTime(2021, 3, 2));
print('You next birthday will be in $duration');
// You next birthday will be in Years: 0, Months: 0, Days: 3
// Find out the difference between two dates
duration = AgeCalculator.dateDifference(
fromDate: DateTime(2021, 1, 2),
toDate: DateTime(2025, 5, 2),
);
print('The difference is $duration');
// You next birthday will be in Years: 4, Months: 4, Days: 0
// Add time to any date
DateTime date = AgeCalculator.add(
date: DateTime(2021, 1, 2),
duration: DateDuration(years: 5, months: 2, days: 1));
print(date);
// 2026-03-03 00:00:00.000
