Answer:
Pentecostals celebrate most holidays. Like all Christians we celebrate Easter and Christmas as they are the main ones. We also recognise Palm Sunday and Pentecost.
We still celebrate all the holidays that regular society celebrates. But to us, They have a much deeper meaning than Easter bunnies and Santa Claus. Halloween is a controversial holiday among Pentecostals because of its origins and I personally choose not to take part in it, but the Lord has a different plan for everyone. For some people He gives an OK on Halloween, others a nope. I just happen to be a nope. I'm not passing judgment or criticizing. That's not loving. But yes we basically celebrate all the regular holidays. Good Friday is a holiday that some churches observe as well.
