With a virtual product on sale on woocommerce the customer buys and that creates an appointment in the planning without date. Then he comes to change his date in his account ...
Or the admin can create an appointment without date (if the plugin allows it).

I want to be able to create an appointment manually without putting a date.
I want the date of this manual appointment to be automatically set to 1970-01-01. Both for the start and end date.

Is this possible and how?

Hello, I went to the site you propose to ask for functions and it made me laugh frankly.

The function is however normal on a management of appointments! 

What I'm looking for is to make an appointment without needing to put a date for a vital product like a school course in order to be able to put the date later either by the customer via his account or by the administrator.

And to be able to choose a fixed fictitious date :-) Anyway I'm not going to waste time to ask for a function that should already exist and that will land in a vague list of requests. My friend, I thank you for having tried to bring an answer but which is useless. I will direct my clients to other plugins and drop my attempts to use Amélie.

Thank you and have a nice day.
