Church Bells at 6:00 a.m. ?!

Hi! I live right off of 7th Ave. on Berkeley Place. This morning (a Saturday), I was awoken at 6:00 a.m. by church bells. They were loud enough to penetrate two white noise machines and Mack's Wax earplugs. This has never happened before, so I'm guessing it's a new practice. Does anyone know which church is responsible for the disturbance? I've written the Old First Reformed Church, St. John's Episcopal, and Grace UMC since they're the closest, but who knows if any of them will confess.
