What I mean familydealz, is that some vicars do and some vicars don't. But it is of course possible to have a christening on a Saturday. It just depends on whether a particular vicar does or not.
I'm godmother at a christening which is on a Saturday so yes it is possible, however, I thought all christenings took place on Sunday's so I was surprised it was on a Saturday.
In my experience most of the Catholic churches hold mass (group) christenings on every other Saturday. I have heard a private christening in a Catholic church is cost prohibitive. (This is in NY)
Most Protestant churches here have them during regular Sunday service, unless the family requests a private one.
Since technically any Christian can baptize(like in an emergency), what difference does the day make?
