+## Use only the **date** part
+In the following example only the **date** part is set. Time is set to by default to `00:00:00`. So the following query compares all entries _archived_ within *a day* (`2021-06-14`):
+
+```javascript
+var start = new Date("2021-06-14");
+var end = new Date("2021-06-15");
+
+db.call_archive.find({archivedAt: {$gte: start, $lt: end}}).pretty();
+
+```
+
+## Use both **date** and **time**
+
+You can also specify the Time in ISO format
+- `new Date("<YYYY-mm-ddTHH:MM:ss>")` - specifies the datetime in the client's local timezone and returns the ISODate with the specified datetime in UTC
+- `new Date("<YYYY-mm-ddTHH:MM:ssZ>") ` - specifies the datetime in UTC and returns the ISODate with the specified datetime in UTC
+
+```javascript
+var start = new Date("2021-06-14T13:13:13Z");
+var end = new Date("2021-06-14T14:13:13Z");
+
+db.call_archive.find({archivedAt: {$gte: start, $lt: end}}).sort({archivedAt: -1}).pretty(); //sort descending
+```
