Frequently Asked Questions
How does the countdown timer work?
The countdown timer calculates the difference between the current time and your event time. It updates every second using JavaScript's setInterval function to provide a live, real-time countdown that shows years, months, days, hours, minutes, and seconds remaining.
Can I count up from a past event?
Yes, if you enter a date and time in the past, the timer automatically switches to count up mode, showing how much time has elapsed since that moment. This is useful for tracking anniversaries, age since birth, or time since a milestone event.
What is the difference between 12-hour and 24-hour format?
12-hour format displays time with AM (midnight to noon) and PM (noon to midnight) labels. 24-hour format (also called military time) displays hours from 00 to 23 without AM/PM labels. You can toggle between them using the checkbox in the tool.
How accurate is the countdown timer?
The countdown timer updates every second based on your device's system clock. It provides accurate time tracking down to the exact second. For the most accurate results, ensure your device's date and time settings are correct.
Can I name my countdown event?
Yes, you can enter an optional event name that will be displayed above the countdown. This helps you organize and identify different countdowns for different events at a glance.
