Pentecost is a season in the Christian religion that happens after Easter. It's named after a special day when Jesus' friends were gathered together and suddenly felt the Holy Spirit. The Holy Spirit is like a special power that helps people feel close to God and do good things.
During Pentecost season, Christians celebrate the coming of the Holy Spirit. It's a time to remember that we can ask for the Holy Spirit's help in our lives, to be kind and loving to others, and to follow Jesus' teachings. People might decorate their churches with the color red, which is a symbol of the Holy Spirit.
One special thing that happens during Pentecost is the reading of the story of when Jesus' friends received the Holy Spirit. Christians listen to this story and are reminded of how they, too, can receive strength and comfort from the Holy Spirit.
Overall, Pentecost is a time to celebrate the special power of the Holy Spirit and to be reminded of Jesus' teachings about love and kindness.
