How the March 21 count works
The counter counts the full days that follow today up to Sunday, March 21, 2027. Today falls on Wednesday, November 4, 2026, and it is left out, so you get 137 days.
After March 21 has gone this year, the countdown uses the next one. On the date itself it notes today is the date, and tomorrow it starts counting to the following year.
The counts of weeks, months and business days use the same two dates. A business day is any Monday to Friday in the span, and the hours figure starts from midnight at the start of today.
The hours figure is counted from midnight today to the opening midnight of March 21. The sleeps figure uses the day count, because every night is one sleep.
Many visitors ask about the days left to March 21 for a holiday. The number above is fresh.
Planning around March 21
Arranging things is easier once you know its weekday. In 2027 the date is a Sunday, and the row of years shows how that shifts over time.
The table of 30, 60, 90 and 100 days covers deadlines that come in blocks of time. Notice periods, probation and payment terms tend to be set to those lengths, which is why dates either side are shown.
The days next to March 21 each have a page. Flip to the day before or after and compare the counts.
Every fourth year adds February 29. A countdown that crosses it includes an extra day, and the page deals with it.
Dates on a weekend may move deliveries, as many banks and offices close on those days.

Dates, weekdays and the calendar
A given date arrives on a different weekday over successive years. An ordinary year is 52 weeks and a day, so the weekday rolls ahead by one, or two after a leap year.
That is why the ten year table is useful before you commit to a plan. A day on a Saturday this year can turn up on a Monday in two years, and your plans change with it.
