Peak days/hours?

For me it had been all over the map. My first placement's call came early on a Monday morning. But it does seem lately that most of the calls come late in the day, late afternoon. My current placement's call came right at 5:00pm, but she didn't arrive until about 4:00am.

Both of the placements we have taken in the last year have come on Monday morning. We have gotten calls all over the place though.
