Definitely no typo! It certainly means something — though in terms of hours, i'm not sure exactly what!
When we talk about 'jours calendaires', we mean 'calendar' days — so '30 jours calendaires means a period of a month, but not necessarily a CALENDAR month; so it might run from say 5th March to 5th April.
My guess would be this means '2 whole days', i.e. 2 periods of 24 hours, not just randomly 48 hrs, say from 11 am Weds. to 11 am Thurs — it seems to me that would possibly be the most logical interpretation in your context.
