What religions do not celebrate holidays?

ANSWER jehovis whitnes i think ANSWER johova witness's ANSWER FROM A JEHOVAH'S WITNESS It is correct that Jehovah's Witnesses do not celebrate the typical "red-letter" days such as Christmas, New Years, etc. We do, however, have a "holiday." It is the annual observance of the death of Jesus Christ and the Lord's evening meal, (aka the "Last Supper") as commanded by Jesus to observe. This is found at Luke 22:19. In my door-todoor ministry, I have encountered a sect of the Christian Holiness religion that also does not celebrate holidays. It's also interesting that the early Quakers and Puritans in America actually outlawed certain holidays such as Christmas and Easter, and early Baptists and Presbyterians spoke out against celebrating these holidays.
