
Adateofrealtimeclockdefinesanactiveperiod.Anindividualperiodisactivefromtheperiodstartingdateto
thefirstnextdateofthebeginningofotherperiods.

Theorderofseasonsandstartingdatesisnotimportant,exceptwhentwodatesareequal.Inthatcasethe
seasonwithahighersuccessivenumberhaspriority,whiletheseasonwithalowernumberwillneverbeactive.

Ifnostartingdateofaseasonisactive,theactiveperiodis1.

Ifthepresentdateisbeforethefirststartingdateofanyperiod,theperiodisactivewiththelaststartingdate.
