I am not able to use this function:
http://www.freepascal.org/docs-html/rtl/dos/weekday.html nor can I find it in the sources.
Does it still exist?
If yes, how to use it? Which unit? DOS does not work.

You will find what you need at unit dateutils.

When I add dateutils to my units Weekday isn't found either (I already tried this yesterday).

The weekday function only exists in the unix version of the Dos unit. It should probably either be removed from its interface, or added to the common part of the Dos unit (there's nothing unix-specific about it).
The generic function to calculate the day of the week is http://www.freepascal.org/docs-html/rtl/sysutils/dayofweek.html

Sysutils has an integer DayOfWeek function, and dateutils has a word DayOfTheWeek function.
Both take a TDateTime parameter (rather than the separate year, month, day parameters of the old dos unit).

That's strange (and not documented).

It should definitely be added (see below).

Yes, but requires an intermediate TDateTime parameter. Weekday would be much easier and direct.

Yes, I already saw this. But this requires a TDateTIme parameter. I have year, month, day directly available.
Why beeing forced to create a TDateTime parameter? Weekday() would not require this and it is documented but does not exist? Why?

It's because the documentation is generated under Linux using fpdoc (which is the only scenario that is used/tested/supported for generating the documentation), and hence fpdoc sees the RTL as it would be compiled under Linux. It has no idea that a particular function may not be present under other OSes (and generally that simply should not happen for common units, or at least be hidden from fpdoc).

It should probably either be removed from its interface, or added to
the common part of the Dos unit (there's nothing unix-specific about
it).
As a first step I added "platform;" modifiers to all unix specific functions in unix' unit dos.
The generic function to calculate the day of the week is http://www.freepascal.org/docs-html/rtl/sysutils/dayofweek.html
IIRC in Delphi dateutils.dayoftheweek is prefered since its introduction in D6 which introduced dateutils and ISO 8601 compatible functions. (the definition of the first day of the week differs from region to region iirc)
But the FPC docs don't mention what the first day of the week is for that function, OR its compliance.

It is monday=1..sunday=7, and the whole unit is supposed to be ISO 8601 compliant.
