[ICAL] Finding all day event started / ended not today

Hi all,

I try to find an all day event that might have started and / or ended not today but is still valid (e.g. holiday of the kids). I fail to filter successfully, current solution

Thing  icalendar:eventfilter:paulfreitoday "Paul frei heute" (icalendar:calendar:paul) [  refreshTime=1, maxEvents=1, datetimeUnit="DAY", datetimeStart=0, datetimeEnd=1, datetimeRound=true, textEventField="SUMMARY",textEventValue="[fF][rR][eE][iI]",textValueType="REGEX"]

Any idea?
