What is a countdown timer?
A countdown timer shows the time remaining until a specific date and time. It is useful for events, deadlines, product launches, reminders, exams, travel plans and project milestones.
How countdown timers work
The timer converts your target date and time into a single UTC moment, compares it with the current time, then breaks the remaining seconds into days, hours, minutes and seconds. The display refreshes every second.
Event countdown use cases
Countdown timers are commonly used for launch pages, conference schedules, application deadlines, invoice due dates, reminders, limited-time offers and remote-team coordination across time zones.
