As an AI language model, I don't have access to future event information, and the schedule for the 2023 Venice Carnival has not been announced yet. However, the Carnival of Venice usually takes place over a period of two weeks, leading up to Ash Wednesday. During this time, the city is filled with people wearing elaborate masks and costumes, and there are a variety of events and activities taking place, such as parades, masquerade balls, concerts, and street performances. It's best to check the official website of the Venice Carnival for updates on the schedule and events for the 2023 edition as the date approaches.
