When is your first mortgage payment due?

Say for example a completion date is this Friday for a new house purchase, when would the first mortgage payment be due. Would it be straight away for at the end of April? Thanks

This is with the halifax if that makes any difference :-)

Makes sense, the first bill will be a month and a few days then. I was wondering if you pay it up front or after the first month
