Countdown to Date

WHAT IT DOES

Countdown to Date gives you a live, real-time countdown to any target date and time. Set a date and time, and the panel updates every second, showing exactly how much time remains in days, hours, minutes, and seconds. The display also shows total days, total hours, total minutes, and total seconds at a glance. Switch to "Count Up" mode to track how much time has elapsed since a past date — perfect for anniversaries, tenure tracking, or milestone celebrations. The panel saves your target date and automatically loads it when you reopen the page, so you never lose track of your countdown.

WHERE IT RUNS

This script runs on every website you visit. Whether you are counting down to a project deadline on task management platforms, tracking a vacation on travel sites, waiting for a product launch on e-commerce pages, or counting up to an anniversary on social media, the panel is always available. It works alongside your existing tools without interfering with your workflow.

HOW TO USE

Select your target date using the date picker and set the time using the time picker. Choose "Countdown to Date" to see remaining time or "Count Up from Date" to see elapsed time. The display updates automatically every second. Use the "Set to Now" button to quickly set the target to the current time. The main display shows days, hours, minutes, and seconds in a large format, while the detail display shows total days, total hours, total minutes, and total seconds. Click any history entry to reload a previously saved target. Use the "Copy Countdown" button to copy the countdown details to your clipboard.

THE LIVE PRECISION TIMER MECHANISM

Countdown to Date uses JavaScript's setInterval function with a 1000ms (1 second) interval to update the display in real-time. Each update calculates the exact difference between the current time and the target time using the Date object's millisecond precision, then decomposes the difference into days, hours, minutes, and seconds. The timer handles both countdown and countup modes correctly — when the target is in the past for countdown mode, the display shows "Time's up!" with a red color. The timer automatically restores the last saved target date when the panel is reopened, and the interval continues running as long as the panel is visible. All calculations account for timezone differences using the user's local system time, ensuring the countdown matches your actual clock.

THE PANEL

The panel is fully draggable and remembers its position per site. It minimizes to a compact floating bubble when collapsed. All settings — target date, mode, and recent targets — persist across browser sessions using GM_setValue storage. Press the Escape key to close the panel. The panel automatically focuses the date input field for quick keyboard entry. The timer runs continuously and updates the display even when the panel is minimized.

PLEASE NOTE

This script requires the free BotGentz extension to run. The countdown uses your computer's local time and does not account for time zone changes. For critical timing, always verify with official time sources. Websites change their structure and behavior over time; if any functionality stops working, the script may need an update. No user data is sent anywhere — all targets and history are stored locally in your browser. The script never reads or modifies password, hidden, or file input fields.
