How the calculation works
Fifteen hours crosses from one part of the day into the next, usually over a night. Timesabout adds 15 hours to the exact moment you load the page, using your device's own time zone, then rolls the date forward if the total passes midnight. Because it recalculates every second, the answer stays correct the whole time the page is open.
