Time until Monday

Monday is the countdown most people would rather run backwards, but it is the one that matters for anything promised for the start of a week. The target is the midnight that opens the day rather than the start of office hours, so add your own commute before the number means much. Under ISO 8601 this is day one of the week and the point at which the week number advances, which is why a European calendar redraws its grid here and an American one does not.

Treat this as a deadline rather than an occasion. Everything that stalled over the weekend moves on a Monday: cheques and card settlement clear, support queues and inboxes are at their fullest, and the meetings booked for the morning are the ones most often moved when something else has gone wrong. Traffic and public transport carry their heaviest weekday loads because schools, shift rotas and delivery schedules all restart at once. The trap worth watching is the holiday. A countdown to next Monday in the United States, Britain or Canada can be pointing at a day when offices, banks and schools are shut, because those three countries deliberately moved a large share of their public holidays onto Mondays.

That clustering was legislated rather than inherited. The American Uniform Monday Holiday Act fixed Washington's Birthday, Memorial Day and Columbus Day to Mondays from 1971, Britain's bank holidays were consolidated the same year and mostly sit on Mondays, and Japan's Happy Monday System moved several national holidays the same way from 2000 to manufacture long weekends. In countries whose weekend is Friday and Saturday, Monday is the third day of the working week and carries none of this weight. What does cluster here everywhere is anything people intend to begin, from gym memberships and courses to the routine appointments and elective lists that health services push towards the front of the week.

The next one falls on the next Monday, and this page counts down to the midnight that starts it in whatever time zone your browser reports.

The English name means the day of the moon, a literal rendering of the Latin dies Lunae, which the Romans had taken from the Greek planetary week. The moon survived the translation in most of Europe, so French has lundi, Spanish lunes, Italian lunedi and German Montag, all saying the same thing in different clothing. English and German simply kept the older word where the Romance languages kept the Latin one.

Languages that number their days put Monday early rather than first, because their counting starts from Sunday. Portuguese calls it segunda-feira, the second, and Greek Deftera has the same meaning. Arabic al-ithnayn and Hebrew yom sheni both mean the second day. Only the ISO convention makes Monday day one, and that is a twentieth-century standardisation rather than an old tradition. It has spread far enough that the two answers now sit side by side in the same software.
