Our online timer category contains many posts featuring countdown clocks for a defined period of time ranging from days to seconds, including minutes and hours of course. Our timers have the shape of three to four circles for seconds, minutes, hours and days. By moving the colors clockwise and counter clockwise using the mouse or, in case of mobile visitors, your finger, our online timers can be set to almost any time you like. They all come with pause, resume, restart and reset functionality, and when the counter reaches zero you will be alerted by a repeating sound. The acoustic notification can be muted though. If you have been searching for an online timer, no need to look any further. Finally, note that our online timers automatically adjusts the neighboring circle if you increase or decrease the time such that a circle overflows or is depleted. Check them out right now!
