Hanukkah begins Dec. 18 and, to celebrate the occasion, Messenger released a Hanukkah chat theme that adds a sweater-themed background to conversations.

When this theme is activated, the chat’s emoji will automatically be updated to the menorah emoji. In addition, three word effects will automatically be added to the chat for the words “candle,” “menorah” and “presents.”

Our guide will show you how to use the Hanukkah chat theme in the Messenger application.

Note: These screenshots were captured in the Messenger app on iOS.

Step 2: Tap “Theme.”

Step 3: Tap the “Hanukkah” chat theme.

Step 4: Tap the “Select” button in the bottom-right corner of the screen.
