** note** I lost access to update my previous flow. Throughout the year I noticed some issues with the date getting cut off, so I have made the required changes to this new flow to mitigate this issue.

The automation "Awtrix: Send Current Date to Awtrix Clocks with Color Themes" triggers whenever the sensor.date entity changes. It formats the current day of the month and the full date (e.g., "OCT 13") and sends this information to the Awtrix clocks (awtrix_clock_1) using MQTT. The date is displayed in a color scheme that corresponds to the current month’s theme (e.g., blue for January, pink for February, red for December). The day of the month is drawn in black, while the formatted date is colored according to the month’s theme. This ensures a visually appealing display based on seasonal events like Christmas, Halloween, or summer.
