Event Countdown Collection

An Event Countdown Collection is a dashboard that lets you create and monitor multiple countdown timers simultaneously. Unlike a single-event countdown timer, this tool gives you an at-a-glance view of all your important upcoming events - birthdays, vacations, project deadlines, product launches, and more - each with its own live countdown display and colour theme.

Add events by giving each a label, target date and time, and a colour theme. Each event appears as a card showing the live countdown (days, hours, minutes, seconds) that updates every second. Events are sorted by nearest deadline by default, so the most urgent countdowns appear first. The cards include a visual progress bar showing how much time has elapsed from 30 days before the target. All your events are saved automatically to your browser's localStorage.

Managing multiple deadlines and events across different calendars can be overwhelming. A single dashboard consolidates all your countdowns in one place, making it easy to see what's coming up and prioritize accordingly. The visual progress bars give you an intuitive sense of urgency, while colour themes help you categorize events at a glance - work deadlines in blue, personal events in green, launches in orange, and so on.

All countdown data is stored locally in your browser using localStorage. No data is uploaded to any server, stored in any database, or shared with third parties. The tool is completely free to use with no signup required, no limits on how many events you can create, and works offline after the initial page load.
