Hello,
It's possible to generate the date in this format to request an appointment:
Tuesday, June 17th, Wednesday, June 18th, or Thursday, June 19th, starting at 9 a.m.
thank you for your help
Hi, and welcome to the forum! 
Yes you can format a date to match the "Tuesday, June 17th" format.
You will want something like dddd, MMMM Do
Here is an example:
It is: {time: dddd, MMMM Do}
You can learn more about formatting options here: Text Blaze | {time}
