A digital hourglass is an online visual timer that mimics the appearance and behavior of a traditional sand hourglass. Instead of physical sand, it uses animated graphics—often with particle effects—to show sand flowing from the top chamber to the bottom, while accurately counting down time.

Simply choose a preset time (1, 3, 5, 10, 15, 30, or 60 minutes) or enter a custom duration, then press Start. The animated sand particles will begin flowing from the upper chamber to the lower one. The digital display shows the exact remaining time, and when the sand runs out, an alert sounds (if enabled).

Visual timers like a sand hourglass provide an intuitive, at-a-glance sense of time passing. The flowing sand animation is calming and helps with focus—ideal for meditation, studying, cooking, timeboxing tasks, or classroom activities. Unlike abstract digital clocks, the visual metaphor of draining sand makes time feel tangible.

Absolutely! Set the timer to 25 minutes (via the custom input) for a classic Pomodoro work session. The visual sand flow provides a gentle, non-distracting way to track your focus period. When the sand runs out, take your 5-minute break, then reset and start again.

Yes. The sand level in the upper chamber decreases proportionally to the remaining time, and the lower chamber fills accordingly. The particle flow rate is constant, and the timer uses the system clock (not frame rate) for precise timekeeping, so it remains accurate even if you switch browser tabs.

Yes! Click the expand icon (⛶) to enter fullscreen mode. This enlarges the hourglass to fill your entire screen—perfect for presentations, classroom use, or when you need a large, visible timer from across the room.

Yes, a pleasant chime plays when the timer reaches zero—provided the Sound Alert toggle is enabled. You can turn it off if you prefer a silent, visual-only notification (the hourglass will flash and a message will appear).

No. This digital hourglass runs entirely in your web browser using HTML5 Canvas and JavaScript. There are no downloads, no Flash, and no plugins required. It works on all modern browsers including Chrome, Firefox, Safari, and Edge.

Yes, the hourglass is fully responsive. On smartphones and tablets, the canvas resizes to fit the screen, and all buttons remain touch-friendly. You can use it as a kitchen timer, study timer, or meditation aid on any device.

While a regular countdown timer only shows numbers, a digital hourglass adds a rich visual metaphor—the flowing sand. This engages your visual senses, reduces anxiety about time passing, and provides a more natural, intuitive understanding of how much time remains. It combines the best of analog and digital timekeeping.
