The calendar collects dated events extracted from filings: periods that ended, registrations that were made, meetings that were called. It is assembled from documents, which shapes both what is in it and what is not.
Confirmed and derived
A date read directly from a document is marked confirmed. A date worked out from a schedule — a period that must fall a certain distance after another — is derived, and marked as such.
Future dates are published only when confirmed. A derived future date is a guess about what a company will do, and a guess printed in a calendar becomes a fact within about a week of being published.
Deadlines make the shape
Filing density is driven by deadlines, not by activity. Days shortly after common fiscal period ends carry many times the filings of an ordinary day, and the pattern repeats every quarter.
That is why a day page here shows the day's total against the typical day, rather than the total alone: without the comparison, a busy Tuesday in a reporting season looks like news.
What is missing, and why
The calendar contains what the connected sources publish. Corporate actions announced by press release rather than by filing are absent. Dividend dates in particular are absent: none of the sources currently connected publishes them in a machine-readable form, so the dividend tool reports that the calendar holds no such entries instead of showing an example.
An absence in this calendar means an absence in our sources. It does not mean nothing happened.
Dates are not the same as dates
Several different dates attach to a single event, and mixing them produces confident nonsense: a period end, the date a document was filed, the date a meeting is held, the date a shareholder register is fixed. Each record here names which kind of date it carries.
