I believe in the EE forms it only requests months? So that's not where my concern is.
Experiences only counts up to lock-in date, which is the date where electronic file of EOI is submitted to CIC server.
I am worrying when the officer review the actual applications (after ITA issues) and finds a few days short of 52 weeks because of the vacation days, that's bad.
That's why leaving 1-2 weeks after completing 1 year of work is always a good move.
CIC counts 30 hrs per week. If any week during the work period is less than 30 hrs, it counts the actual hours. otherwise it counts 30.
