Question

It's 1:00PM Monday. What will be the exact time and day 1 million seconds later?

Answer 1

That would be 10^6 s/86,400 s/day = 11.57407 days later. That is 11 days and 13.777778 hours. Thirteen hours after 1:00 PM Monday is 2:00AM Friday. Add 0.77778 hours (46.667 minutes) to that.
That makes 2:46 AM Friday + 40 seconds
