Here in my region it is Thursday. At the time of writing, the time is 09:30 a.m. and the date is May 10, 2018. At 12:00 a.m. at night the date will change and it will be May 11, 2018.
My question is, will the day also change? Will it be Friday after 12:00 a.m. [here in my region] (when the date is May 11, 2018) or will Friday fall with the sunrise (here) that is around 05:30 a.m.?
In short, does the day change with date at 12:00 a.m. or it changes with the sunrise? If it changes with date now question is, at 12:00 a.m when we have May 11 here, will that be 'Friday night' or 'Thursday night'? If it turns 'Friday night' then question is, does a night come twice? Since on May 11 after sunset it will be Friday evening & night here in this region...
