Between

Validates ranges. Most simple example:

v::intVal()->between(10, 20)->validate(15); // true

The type as the first validator in a chain is a good practice, since between accepts many types:

v::stringType()->between('a', 'f')->validate('c'); // true

Also very powerful with dates:

v::date()->between('2009-01-01', '2013-01-01')->validate('2010-01-01'); // true

Date ranges accept strtotime values:

v::date()->between('yesterday', 'tomorrow')->validate('now'); // true

A third parameter may be passed to validate the passed values inclusive:

v::date()->between(10, 20, true)->validate(20); // true

Message template for this validator includes {{minValue}} and {{maxValue}}.
