How the calculation works
Seventy-two hours is three full days — a common deadline window. Timesabout adds 72 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.
