busday_count(begindates, enddates, weekmask='1111100', holidays=[], busdaycal=None, out=None)
If enddates
specifies a date value that is earlier than the corresponding begindates
date value, the count will be negative.
The array of the first dates for counting.
The array of the end dates for counting, which are excluded from the count themselves.
A seven-element array indicating which of Monday through Sunday are valid days. May be specified as a length-seven list or array, like [1,1,1,1,1,0,0]; a length-seven string, like '1111100'; or a string like "Mon Tue Wed Thu Fri", made up of 3-character abbreviations for weekdays, optionally separated by white space. Valid abbreviations are: Mon Tue Wed Thu Fri Sat Sun
An array of dates to consider as invalid dates. They may be specified in any order, and NaT (not-a-time) dates are ignored. This list is saved in a normalized form that is suited for fast calculations of valid days.
A busdaycalendar
object which specifies the valid days. If this parameter is provided, neither weekmask nor holidays may be provided.
If provided, this array is filled with the result.
An array with a shape from broadcasting begindates
and enddates
together, containing the number of valid days between the begin and end dates.
Counts the number of valid days between :None:None:`begindates` and :None:None:`enddates`, not including the day of :None:None:`enddates`.
busday_offset
Applies an offset counted in valid days.
busdaycalendar
An object that specifies a custom set of valid days.
is_busday
Returns a boolean array indicating valid days.

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
