Q-drop 88 does not read, '10 days of darkness', it reads '10 days. Darkness.' And drop 97 reads, '10 days. Darnkess.'
Could it be 10 days 'until' darkness? So, yesterday, Good Friday, was 10 days 'until' darkness.
I'm not date-fagging, we will have 'darkness' in nine days, now!
It could have multiple meanings.
