My neighborhood megachurch, which is very multiethnic and seems to serve the poor well, has plenty of worship times on Saturday and some weekday evenings. I'm Orthodox Christian. We also have worship on Saturday evening and some weekday evenings; it's called "vespers", and it's an ancient tradition of the church. Easter Sunday starts at 10pm Saturday night and the after-worship feast goes until dawn the next morning. Some Orthodox churches like ours still do it that way, the old way.
