How many days until Valentine's Day?
This page counts the days, hours, minutes and seconds until 14 February begins in your own time zone, the usual meaning of "days until Valentine's Day". It updates every second, needs nothing typed, and as soon as the day has passed it starts counting to next year's 14 February by itself.
14 February: where the date comes from
Valentine's Day is the feast day of Saint Valentine, fixed on 14 February in the Western church calendar, and it became a day for love letters in the late Middle Ages, when Chaucer linked it to birds choosing their mates. It falls on the same date every year, so the countdown never needs adjusting.
Customs differ by country: in Korea and Japan, women traditionally give chocolate on 14 February and men reply on White Day, 14 March; Korea adds Black Day on 14 April for singles. Those dates make good custom countdowns on the countdown page.
Which time zone does the countdown use?
Midnight in the time zone your device reports, so a reader in Seoul and a reader in Lisbon each see the hours to their own midnight, nine hours apart. The target is written under the digits with its zone abbreviation, for example "KST (UTC+09:00)", so you can check it at a glance.
To count to Valentine's Day somewhere else, such as a family video call at midnight in another country, make a custom countdown on the countdown page with that zone selected; its share link carries the exact moment, and anyone who opens it sees the same instant converted to their clock.
It stays exact in the background and rings at midnight
The remaining time is recomputed from the clock every time the page draws, so a background tab or a locked phone cannot make it drift; when you come back, the digits are simply right. Over long spans the day count is a true count of 24-hour periods, which is why a daylight-saving change in between can show as 84 days 23 hours rather than 85.
During the last 100 hours the alarm is pre-scheduled on the browser's audio clock and backed by a system timer and a desktop notification, so if the page is open at midnight it rings on time, even in a background tab on a computer. Choose the sound and volume under Alarm; on an iPhone keep the tab in front, because Safari pauses hidden pages.
On the day itself, and the year after
From midnight the page shows a greeting instead of the countdown, with how long ago the day began, and a small line with the days until next year's Valentine's Day. Twenty-four hours later it switches back to counting, so a bookmark or a classroom display never needs resetting.
Reservations, deliveries and anniversaries
Restaurants fill up two to three weeks ahead, and flower deliveries for the 14th are usually ordered by the 10th at the latest, so the day count here is the number to watch. Because the countdown ends at the start of the day, the evening itself is still 18 hours or so after zero.
For a wedding anniversary or the day you met, a custom countdown to that date shows the days left, and a countdown to the past date shows the days since, for example 1,000 days together. Both share the same link format.
Other countdowns and time tools
The countdown page counts to any date and time you choose, in any time zone, and also counts the days since a past date. For a length of time starting now, such as 10 minutes, use the timer; the stopwatch measures how long something takes. New Year, Christmas, Halloween and Valentine's Day each have a page like this one.
