Suppose this is your model:
var EventSchema = new Schema({
title: String,
startDate: Date,
endDate: Date
});
I would like to throw in a date (as simple as like '24-12-2012') and then retrieve every event that started or proceeded at that single day.
How do you do that?
Sure:
First read up on mongo query syntax for dates, here is a how-to for date ranges: http://cookbook.mongodb.org/patterns/date_range/
Then translate that mongo syntax into mongoose.
Event.where('startDate').lte(yourDate).exec(callback); //should do the trick
Now you just need to parse date strings to javascript dates. There are some cool libraries to do that, I believe that moment.js won't have a problem with that date string.
Oh, I forgot the last bit of magic: Put that query into a static method attached to your Event model, so from now on you can just call
Event.earlierThan(yourDate, callback); //Where your custom static is called 'earlierThan'.
