CIC state it is calculated in months, as does their wizard, and like I said above, each case is unique and other factors may be taken into consideration.
The latter is also found on their website.
The EE rules are the exact same rules they have been using for years to calculate CEC experience. They rules aren't new and we've seen tons of examples here of who CIC accepts and refuses. You need 52 weeks of work (it's not calculated in months). Each week must consist of a minimum of 30 hours to be counted as full time. Part time weeks can be combined to make full time weeks. However extra hours from full time weeks cannot be carried over into other week. It's pretty straight-forward.

As you can already see from the answers most forum members believe that work experience is counted in weeks unless you provide a link that states work experience is counted in months.
