fd()
computes the number of work-free days per week for standard
and micro versions of the Munich ChronoType Questionnaire (MCTQ).
fd(wd)
wd |
An integerish
|
Standard MCTQ functions were created following the guidelines in Roenneberg, Wirz-Justice, & Merrow (2003), Roenneberg, Allebrandt, Merrow, & Vetter (2012), and from The Worldwide Experimental Platform (theWeP, n.d.).
\mu
MCTQ functions were created following the guidelines in Ghotbi
et al. (2020), in addition to the guidelines used for the standard MCTQ.
MCTQ^{Shift}
functions were created following the
guidelines in Juda, Vetter, & Roenneberg (2013), in addition to the
guidelines used for the standard MCTQ.

An integer
object corresponding to the
difference between the number of days in a week (7) and the number of
workdays (wd
).
Roenneberg, Allebrandt, Merrow, & Vetter (2012) and The Worldwide
Experimental Platform (n.d.) guidelines for fd()
(FD
) computation are
as follows.
FD = 7 - WD
Where:
FD
= Number of work-free days per week.
WD
= Number of workdays per week ("I have a regular work schedule and
work ___ days per week").
