You can compose with chance.year for interesting combinations. For example, let's say we want to get the birthdays of some renaissance artists (born between 1450 and 1500). We can generate a year and then get a birthday from that year:
var year = chance.year({ min: 1450, max: 1500 });
chance.birthday({ year: year });
=> Wed Aug 27 1484 11:24:14 GMT-0400 (EDT)
// Could be simplified down to one line
chance.birthday({ year: chance.year({ min: 1450, max: 1500 }) });
=> Fri Nov 26 1469 09:17:13 GMT-0500 (EST)
Can specify maxAge and/or minAge. This will return a date which yields to an age between the given range. Attention on limits: the full day of birthdays are considered to be part of the allowed range (from the first millisecond of the minimum date to the last second of the maximum date).
chance.birthday({minAge: 18, maxAge: 21});
