I want to know the answer to the following question:
Do Protestants celebrate Marian feasts or not?
All the background I'm provided with is that "While the Catholic Church celebrates the Feast of the Assumption on August 15, some Eastern Catholics celebrate it as Dormition of the Theotokos, and may do so on August 28, if they follow the Julian calendar.". Is that enough to answer the question?
Answer: no
