This countdown shows the time remaining until any date and time you choose, ticking every second in days, hours, minutes, and seconds. Name the event, pick a target, and copy the link: the name and target are stored in the URL, so the same countdown opens on any device. Presets jump to the next New Year, Christmas, Halloween, Fourth of July, or the coming Friday at 5 pm. Below the clock it lists the total seconds, minutes, hours, days, and weeks left and the target's weekday. It suits launches, weddings, trips, exam dates, retirement, and anything else worth counting down to.
The target is built from the date and time fields as a local Date (new Date(year, month - 1, day, hour, minute)), so it refers to that wall-clock moment in your own time zone. Every second the page subtracts the current time from the target to get a remaining span in milliseconds and splits it with integer division: days = floor(ms / 86,400,000), then hours, minutes, and seconds from the remainder. Because the target is a fixed instant, a daylight-saving change during the wait shortens or lengthens one day by an hour, exactly as the clock on the wall does. When the remaining time reaches zero the display switches to 'It's here' and a short tone plays.
The link stores the date and time, not the instant, so a person opening it elsewhere sees a countdown to that wall-clock time in their own zone. For a global event at one instant, tell each person the time in their zone or use the Time Zone Converter on this site.
Days are whole 24-hour blocks of remaining time, not calendar days. A countdown showing 3 days 2 hours at 10 pm shows 2 days 18 hours at 6 am the next morning; the calendar-day view is the target date itself, which does not change.
The countdown is computed from the target and the current clock each time it runs, so nothing is lost by closing the page. Reopen the same link and it continues from the correct remaining time. The tone at zero only plays while the tab is open.
The clock shows 'It's here' and then the time elapsed since the target, so the page doubles as a count-up. To restart, pick a new date or a preset; the New Year preset always targets the next January 1 at midnight.
