Firebase Firestory Query Where Stored Timestamp Is In The Past

I need to delete all Documents which have a timestamp (stored in a field) prior to today. The timestamp is created in the Firestore GUI. The following query doesnt return any docs.

Solution 1:

Whenever passing a date to Firestore, you should pass in an actual Date object. Date.now() returns a timestamp, which is just a number and not a Date object itself. To get the actual Date for the same value, use new Date(). So:

collectionRef
  .where('timestampFieldName', '<', new Date())
  .get()
