File: documentdb/latest/developerguide/isoWeek.md

Summary

Added new documentation page for the $isoWeek operator in Amazon DocumentDB, including description, MongoDB shell example, and code examples in Node.js and Python with connection strings

Security assessment

This change adds documentation for a date/time operator ($isoWeek) and includes standard connection examples with TLS parameters. There is no evidence of addressing a security vulnerability, weakness, or incident. The TLS parameters shown (tls=true, tlsCAFile=global-bundle.pem) are standard secure connection practices but don't represent new security documentation or address a specific security issue.

+# $isoWeek
+
+The `$isoWeek` operator in Amazon DocumentDB returns the ISO week number for a date. The ISO week date system is a way of numbering weeks in a year, in which the first week of a new year is the week that contains the first Thursday of that year. This is different from the Gregorian calendar, where the first week of a new year is the week that contains January 1.
+
+**Parameters**
+
+None
+
+## Example (MongoDB Shell)
+
+The following example demonstrates how to use the `$isoWeek` operator to retrieve the ISO week number for a given date.
+
+**Create sample documents**
+    
+    
+    db.dates.insertMany([
+      { _id: 1, date: new ISODate("2022-01-01") },
+      { _id: 2, date: new ISODate("2022-12-31") },
+      { _id: 3, date: new ISODate("2023-01-01") }
+    ])
+
+**Query example**
+    
+    
+    db.dates.aggregate([
+      {
+        $project: {
+          _id: 1,
+          isoWeek: { $isoWeek: "$date" }
+        }
+      }
+    ])
+
+**Output**
+    
+    
+    [
+      { "_id": 1, "isoWeek": 52 },
+      { "_id": 2, "isoWeek": 52 },
+      { "_id": 3, "isoWeek": 1 }
+    ]
+
+## Code examples
