+### Controlling single-digit vs double-digit day or month
+
+Use `numeric` for single digits and `2-digit` for leading zeros.
+The output may still follow the locale's style.
+For example, `en-GB` often pads even with `numeric`.
+
+```js
+const date = new Date(Date.UTC(2012, 1, 2, 3, 0, 0));
+
+// Single-digit day and month
+const options = {
+  timeZone: "UTC",
+  year: "numeric",
+  month: "numeric",
+  day: "numeric",
+  hour: "numeric",
+  minute: "numeric",
+};
+console.log(date.toLocaleString("en-US", options));
+// Example output: "2/2/2012, 3:00 AM"
+// The exact date and time may shift depending on your local time zone.
+
+// Double-digit day and month
+options.month = "2-digit";
+options.day = "2-digit";
+options.hour = "2-digit";

+console.log(date.toLocaleString("en-US", options));
