Q1: How does the countdown timer work?
Enter a target date and time, and the countdown automatically updates every second, showing days, hours, minutes, and seconds remaining until that moment. The timer runs continuously in your browser and updates in real-time.
Q2: What happens when the countdown reaches zero?
When the target date/time is reached or passed, the countdown shows 0d 0h 0m 0s. The timer continues to run, so if the target is in the past, it will show zeros. You can set a new target date/time to start a new countdown.
Q3: Does the countdown work if I close the page?
No, the countdown only runs while the page is open in your browser. When you close or refresh the page, the countdown stops. For persistent countdowns, you'd need to save the target date and reload it, or use a dedicated countdown app.
Q4: Can I use this for multiple countdowns?
This calculator shows one countdown at a time. To track multiple events, you can open multiple browser tabs, each with a different target date/time. Each tab will run its own independent countdown timer.
Q5: How precise is the countdown?
The countdown updates every second, so it's precise to the second level. However, browser performance, system load, and tab inactivity can cause minor delays. For most purposes, the precision is sufficient and appears real-time.
Q6: What timezone does the countdown use?
The countdown uses your browser's local timezone, which is based on your device's time settings. When you enter a date and time, it's interpreted in your local timezone. For timezone-aware countdowns, use a timezone converter first.
