Counting

Change either and every figure above updates. Most date tools pick a zone and a counting rule silently, which is why two sites can answer the same question with different numbers.

Why other sites give different answers

Ask the web how many days there are until Christmas and you get five different numbers from the pages ranking for the question. They are not all wrong. They are answering slightly different questions and none of them says which.

Two things account for almost all of it.

Where you are standing

A date is not an instant. 25 December begins in Kiritimati twenty-six hours before it begins on Baker Island, so for a whole day of real time two people on Earth genuinely have different numbers of days left. A page that counts in one fixed zone is wrong for everybody outside it. Every countdown here names its zone and lets you change it.

Whether today counts

Counting from Monday to Thursday gives three days if you count the nights and four if you count the dates. Both conventions are in real use: contracts and court rules often count inclusively, everyday speech does not. The default here is that today does not count, which matches what people mean by "days until", and the toggle is on the face of the readout rather than buried.

There is a third figure that gets mixed in, which is clock time still to run. That is always one lower than the calendar-day count once part of today has gone, and it is where a lot of the disagreement comes from. Each countdown shows the calendar days as its answer and the clock time as a separate sub-reading, so the two are never confused.
