-  * `expression`: The date field or expression from which to extract the day of the year.
-
-
-
-
-## Example (MongoDB Shell)
-
-This example demonstrates how to use the `$dayOfYear` operator to extract the day of the year from a date field in an Amazon DocumentDB collection.
-
-**Create sample documents**
-    
-    
-    db.weather.insert([
-      {
-        "temperature" : 97.5,
-        "humidity": 0.60,
-        "date" : new Date("2023-03-15")
-      },
-      {
-        "temperature" : 82.3,
-        "humidity": 0.75,
-        "date" : new Date("2023-12-31")
-      }
-    ])
-
-**Query example**
-    
-    
-    db.weather.aggregate([
-      {
-        $project: {
-          dayOfYear: { $dayOfYear: "$date" }
-        }
-      }
-    ]).pretty()
-
-**Output**
-    
-    
-    { "_id" : ObjectId("642b86fc7d8e07af279bbe63"), "dayOfYear" : 74 }
-    { "_id" : ObjectId("642b86fc7d8e07af279bbe64"), "dayOfYear" : 365 }
