For me, Saturdays are my favourite day, specifically the afternoon into the night.
Friday night though I like way more than Sunday since Friday night you still have the entire weekend to look forward to.
Although in terms of least favourite day of the week, some might say Monday, but I'd say it's Tuesday because everyone treats Monday like a Monday, and being off for the weekend makes you feel refreshed by Monday. Once Tuesday rolls around it feels so long until the weekend.
