what are the official party days for Easter this year?

[2020]

We have friends who want to visit us in Las Terrenas in April. I totally forgot about the festivities in April

Good Friday is on April 15th, and Easter is Sunday, April 17th

What days exactly are the beaches packed and the roads closed going into Playas Las Ballenas?

The last weekend of Semana Santa, which would be the 16th and 17th this year, are always the busiest with the beaches packed everywhere. I avoid Cabarete and Sosua that weekend.
