How to Query MongoDB Documents Based on Their Creation Date Using ObjectId?

Querying MongoDB ObjectId by Date

ObjectIds in MongoDB embed the timestamp of their creation. This allows you to query documents based on the date the ObjectId was created.

For detailed implementation, refer to "Popping Timestamps into ObjectIds." Here's a brief overview in JavaScript:

<code class="javascript">function objectIdWithTimestamp(timestamp) {
    if (typeof(timestamp) == 'string') {
        timestamp = new Date(timestamp);
    }
    var hexSeconds = Math.floor(timestamp/1000).toString(16);
    var constructedObjectId = ObjectId(hexSeconds + "0000000000000000");
    return constructedObjectId
}

/* Find all documents created after midnight on May 25th, 1980 */
db.mycollection.find({ _id: { $gt: objectIdWithTimestamp('1980/05/25') } });</code>
