return query based on date

Just been implementing something similar in Mongo v3.2.3 using Node v0.12.7 and v4.4.4 and used:

{ $gte: new Date(dateVar).toISOString() }

I'm passing in an ISODate (e.g. 2016-04-22T00:00:00Z) and this works for a .find() query with or without the toISOString function. But when using in an .aggregate() $match query it doesn't like the toISOString function!

You probably want to make a range query, for example, all items created after a given date:

db.gpsdatas.find({"createdAt" : { $gte : new ISODate("2012-01-12T20:15:31Z") }});

I'm using $gte (greater than or equals), because this is often used for date-only queries, where the time component is 00:00:00.

If you really want to find a date that equals another date, the syntax would be

db.gpsdatas.find({"createdAt" : new ISODate("2012-01-12T20:15:31Z") });
