The sun dial worked during daylight, but how did people agree on what time it was at night before clocks were invented?

    THE Big Dipper’s angle can be used to tell time at northern latitudes. It stays in the sky all night. I was told by a Blackfoot elder that they used it as a clock on clear nights.

    The position changes with both time of night and time of year. Regular observers can tell time by the angle the constellation sits at.
