Safe Date.js

An special wrapper for the Date.js library that loads the Date.js Date extensions into an special type giving you access to the Date.js magic without screwing Date type of the Node.js application. It's safe to be used with type sensitive modules like Mongoose.js.

See the datejs site for more information.


npm install safe_datejs


Use the function AsDateJs to convert your date to Date.js and use AsRegularDate when you are finished working with Date.js. Both functions will return shallow copies.


var datejs = require('safe_datejs');

var today = new Date(2011, 11, 12, 0, 0, 0, 0);
var wrappedToday = today.AsDateJs();
console.log('Is today:',;

var tomorrow = wrappedToday.clone().add({days:1});
console.log('Wrapped Tomorrow:', tomorrow.toString(), 'is date regular Date: ', (tomorrow instanceof Date));

var unwrappedTomorrow = tomorrow.AsRegularDate(); 
console.log('Unwrapped Tomorrow:', unwrappedTomorrow.toString(), 'is date regular Date: ', (unwrappedTomorrow instanceof Date));


Is today: false
Wrapped Tomorrow: Tue Dec 13 2011 00:00:00 GMT-0500 (COT) is date regular Date:  false
Unwrapped Tomorrow: Tue Dec 13 2011 00:00:00 GMT-0500 (COT) is date regular Date:  true
