Testing out best times to post on Facebook

Trying out according to the stats here

Before I read such articles, I’ve been posting promotions and ads of my online fashion store on Facebook and Instagram?since 2012. So far I get the most views:

1. when I get friends to share my posts,
2. after meal times, specifically after dinner on the weekdays and after lunch on the weekends
3. just after working hours when people are commuting back home

The least views:

1. After 2am weekend nights
2. During regular working hours
3. After Facebook tweaked their newsfeed algorithm
