Hello AA,
Thank you for sharing your situation and question with us.
As you may know, one of the requirements for Citizenship is that you have lived in Canada as a PR for at least 3 years out of the 4 years (1,095 days) right before the day you apply.
It may be best and most helpful to try and use the Citizenship and Immigration Canada (CIC) Residence Calculator . This may help you with your calculation.
It may also be helpful to contact the the Citizenship and Immigration Canada (CIC) Call Centre directly.
I hope this information is helpful. Please let us know if you have further questions and if there is any follow up to your question/situation.
