Experience Calming Time Flow with a Digital Hourglass

A digital recreation of the classic hourglass. Watch golden sand grains fall from the top bulb to the bottom as time passes. The realistic animation includes individual falling particles and accumulating sand piles.

The hourglass, also known as a sand timer or sand clock, has been used since the 14th century. Unlike digital clocks with cold numbers, an hourglass provides a calming, physical intuition of time passing. Perfect for board games, classrooms, meditation, tea steeping, and productivity sprints.

How to Use the Hourglass Timer

Select a preset duration (1 min, 3 min, 5 min, 10 min) or enter a custom time in m:ss format.

Click Start or press Spacebar to begin watching the sand stream through the hourglass neck.

Observe the top chamber drain as the bottom sand mound accumulates in real time.
