Knowing your dates for each carnival festivity is super important. The "Carnival Calendar" is a must to have in this case. It gives you dates for each country's celebration day to plan accordingly and arrange for accommodations and flights for each country's festivity you will attend. Knowing this information can save you a lot of time and, most importantly, money! With the calendar, you can book in advance for all your necessary accommodation. If you wait last minute, you may not be able to get a cot for rent, because these places fill up quickly and true "Carnivalistas" do not play about planning and booking their dates, etc. I've attached an example of last years calendar because due to the pandemic 2021's non-existent but I'm praying a 2022 carnival year will happen.
