Frequently Asked Questions
How does the calculation work?
The tool calculates the difference between today and a target date. If the target is in the future: 'X days remaining'. If today: 'It's today!'. If already passed: 'X days ago'. Calculation uses UTC time for consistent results worldwide.
Can I add multiple countdowns?
Yes. Click 'Add Countdown' to add multiple target dates. Each countdown displays independently with a name and remaining days. All data is saved in browser LocalStorage and persists across page reloads.
What date formats are supported?
A date picker is provided for calendar selection. Manual input of YYYY-MM-DD format (e.g., 2026-12-25) is also supported. The tool validates dates automatically and calculates the difference.
Does the countdown show hours and minutes?
The current version calculates in days only. For hour/minute/second precision, use our Countdown Timer tool. Days countdown is best for holidays, birthdays, project deadlines - scenarios where day-level precision is sufficient.
Where is my data stored? Is it safe?
All data is stored in your browser's LocalStorage only, never uploaded to any server. Data persists even after browser restart. Clearing browser data will also clear saved countdowns. This is a purely client-side application.
