Hi ​@Fleur53013 - Thanks for reaching out!

At this time, there is not a way to manually change this, however this has been requested before, I’ve sent it off to our product team to review. :) 

Right now, this is based on the invitee's location (determined via their IP address) the calendar can display with either Sunday or Monday as the first (left most) day of the week. This is done automatically and can not be manually adjusted.

IP addresses determined to be located in the countries on this list will have the calendar displayed as Sunday-first. All other counties not included on this list will display as Monday-first.

Sunday-first Country List:

• US
• Canada
• Latin American countries
• China
• Japan
• Israel
• Jamaica
• Taiwan
• Thailand
• Hong Kong
• Macau
• Egypt
• South Africa
• Philippines
   

Let me know if you have any questions!
