I need to add my wifes work shifts into my calendar. They are listed on a
text file and there is certain pattern it follows e.g.

31 Fr Duty 1655 AY2155 HEL 1755 AGP 2130 757 AY2156 AGP 2230 HEL 0355
757

01 Sa 0425 11:30 29:35
02 Su OFF 0000 0000
03 Mo Duty 0635 1155 05:20 13:30 AY661 HEL 0735 CPH 0815 32S AY662 CPH
0855 HEL 1125 32S
04 Tu OFF 0000

Is there a possibility to fill these into a calendar with a script and here
can I find such?
Thank's in advance
