You'll need to set up a calendar of availability if you want to receive meeting requests to connect at times when you are most interested in receiving them. You are not guaranteeing you will be available, but rather these are your generally preferred times.
1) Go to your profile.
2) Click on Schedule Availability.
3) The first time you access the calendar a pop-up appears asking you to select your Time Zone. If you ever want to change it, go to Account Settings and Time Zone per below.
4) After choosing your Time Zone, the calendar selector will appear. Select days and times during a typical week you want to show on your calendar and make sure you click Save Changes. When someone looks at your calendar they will see this typical week of available days and times replicated for the next 4 weeks.
