# MaxAge

- `MaxAge(int $age)`
- `MaxAge(int $age, string $format)`

Validates a maximum age for a given date. The `$format` argument should be in
accordance to PHP's [date()][] function. When `$format` is not  given this rule
accepts [Supported Date and Time Formats][] by PHP (see [strtotime()][]).

```php
v::maxAge(12)->validate('12 years ago'); // true
v::maxAge(12, 'Y-m-d')->validate('2013-07-31'); // true

v::maxAge(12)->validate('13 years ago'); // false
v::maxAge(18, 'Y-m-d')->validate('1988-09-09'); // false
```

Using [Date](Date.md) before is a best-practice.
This rule does not accepts instances of [DateTimeInterface][].
