Having trouble computing age to be converted to year

Here is my native query

[ { "$project": { "_id": 1, "Birthday":1,
"age": {"$divide": [{ "$subtract": [ "$$NOW", "$Birthday" ] },(365 * 24 * 60 * 60 * 1000")] },
"wholeAge": {"$floor" : {"$divide": [{ $subtract: [ "$$NOW", "$Birthday" ] },(365 * 24 * 60 * 60 * 1000")] }} }}]

Error is Unable to parse query: JSON reader was expecting a value but found '('.

Is there a workaround for this?

The divide is to convert the milliseconds to year.

Nevermind. Got it already to work using this query below

[ { "$project": { "_id": 1, "Birthday":1,"wholeAge": {"$floor" : {"$divide": [{ $subtract: [ "$$NOW", "$Birthday" ] },{"$multiply":[365, 24, 60, 60, 1000]}] }} }}]
