When we have any mail it’s usually delivered by about 09:30 Monday to Saturday unless our regular postie is off - then it can be as late as 4pm.
Ours is about midday he arrives in a little red van like Postman Pat… no cat though 
Ours arrives at different times each week. I think they change the posties’ rounds weekly or something.
Some weeks it arrives at 8ish
Some weeks mid morning
And sometimes more like midday or even later.
I find I don’t look forward to it like I used to anyway because everything important comes via e-mail or online these days.
Christmas and birthday times are the best!
