Global Clock

A universal 24-hour analog clock that tells you the time everywhere!

Run in Browser

This app visualizes the rotation and axial tilt of the Earth relative to the Sun in real time (assuming your system's clock is accurate).

The Earth is rendered with an azimuthal projection centered on the South pole, so it will rotate clockwise and so lines of longitude will radiate in straight lines from the center. It is roughly aligned to a 24 hour clock, with midnight at the top and noon at the bottom.

There is also a clock face which displays the local time (again, depending on your system clock) in a 24-hour analog format, so the hour hand is synchronized with the rotation of the Earth.
