Providing Employment Info to Express Entry & Unpaid Leave

Hello Guys,

I have a quick question on how to add my work history. Here are the details.

Employment 1 : 27 Feb 2017 - 29 Dec 2018 (During 2017 I didn’t work during Oct & Nov and during 2018 I didn’t work for a month)
Employment 2 : 1 Apr 2019 - 20 Sep 2019
Employment 3 : 23Sep2019 - current

It seems like I am eligible for 3 Year work experience but how do I record these months which I didn’t work.
Should I include Feb 2017 as start date even though I only worked for couple of days in Feb 2017?

Thanks for your help.
