Holiday Countdown

A family celebration

Count down to a birthday, wedding or reunion. Give relatives the same deadline even when they live in different time zones, and send a PNG when a simple picture is easier than a link.

Travel and the first day away

Use your destination’s time zone for departure plans or the start of a break. Keep separate events for leaving home and arriving; the countdown is a planning aid, not a replacement for your ticket.

A classroom calendar

Put a school event or holiday on a large display. Children can watch the remaining time change while you use the occasion to discuss dates, calendars and why a public holiday can move.

A launch or team deadline

Set the launch time in the team’s agreed zone, rather than leaving everyone to interpret “Friday at nine.” Calendar downloads and exact-time links help remote colleagues work toward the same moment.

Holiday dates by year

Our curated selection covers 18 countries, with explicit regional calendars where needed. Changing the year loads that year’s dates; a moving holiday is not copied blindly from the previous year.

Actual date or observed day off

A holiday can fall on a weekend while the day off moves to another weekday. Choose the date basis and check the separate celebration date shown on observed presets. Local rules still deserve a check before booking.

Named time zones

A zone such as Europe/London carries daylight-saving rules; a fixed offset does not. Search our time-zone list, then inspect the resolved deadline. A skipped hour is invalid: choose another time. When an hour repeats, explicitly choose its first or second occurrence.

Editable events and useful progress

Save several plans, edit a deadline, duplicate an event or undo a removal. Progress measures the interval from creation to the deadline. It is not a percentage of the holiday year and does not restart every second.

Alerts you can test

Choose from our alarm sounds, adjust volume and try a preview. Enable browser notifications separately. Keep the tab open: permission, speaker settings, power saving and browser suspension can affect delivery.

Calendar, picture and sharing

The calendar file contains the exact UTC instant, which your calendar app displays in its own zone. PNG downloads include the event, deadline, remaining time and ClockTools branding. Shared links do not enable alerts or save events automatically.

A holiday can be a rule, not a fixed date

A wall calendar looks like a collection of numbered boxes, but many holidays are defined by a weekday rule. US Memorial Day is the last Monday in May; Thanksgiving is the fourth Thursday in November. Their dates change with the year, so “May 25” cannot stand in for Memorial Day forever.

The distinction matters when you plan well ahead. A copied date can look believable while being several days wrong. Our presets are generated for each supported year, and the selected country or region travels with the date. A birthday is usually a fixed calendar date; a public holiday may require both a year and a rule.

The celebration and the day off are different ideas

The date of a celebration answers when an occasion occurs. An observed date answers when a particular calendar grants the day off. Those answers can differ around a weekend, and different countries or regions can apply different arrangements.

For a family gathering, you may want the celebration itself. For an office closure, the observed date can be more useful. Neither choice describes every employer, school or religious community. Our two date modes make that distinction visible instead of silently replacing one date with the other. Always confirm an official calendar when leave, contracts or travel costs depend on it.

Calendars, lunar traditions and the length of a day

Not every tradition follows a fixed date in the civil calendar. Easter calculations use ecclesiastical calendar rules; the “full moon” in those rules is not simply the next astronomical full moon. Other festivals follow lunar or lunisolar calendars, and some dates depend on an official announcement or local observation. We do not invent a preset when the relevant date is uncertain.

There is another subtlety: our days are complete 24-hour intervals remaining until an instant, not the number of date boxes you cross on a calendar. A daylight-saving change can make the interval between two local midnights 23 or 25 hours. Keeping the named zone and exact deadline visible helps explain why those two ways of counting can differ.
