I do not know what you mean specifically by 'one of the boons' - and if it lasts 45 days, it should theoretically expire, today. I feel it lasts far too long for how inconsequential it is - the benefits (that I've observed/confirmed) seem fairly insignificant for locking someone out of ritual blessings for 45 days.
If it doesn't expire today, I'll post again. Thank you!
Edit: I did Manual Math™ and have determined it should expire the 31st or 1st, and if it doesn't, I'll update here.
45 days for what is arguably a meaningless and inconsequential buff (Or whatever it's meant to do doesn't actually work - not as if there's documentation) is probably too much for how much you are locked out of.
