Call for System Time and Date

[AlxGerfeen5017 0]

First let me say Hi and that I hope this is the right spot for me to post something like this. I am creating my game in rpg maker mv and have an idea for a vendor in the end game. He will function almost like xur from destiny 2, where he shows up at a specific time, however he will have a fixed location. I want him to be availible in the game starting at 1am on a saturday morning, and ending at 11pm that same day. this would occur every saturday. All I need to know is how do I create this event that would be a parallel process and search for the system date and time, and then if the day and start time are valid it turns a switch on. then turns that switch off when it is 12:00am Sunday morning. PLEASE HELP i do not know how to code.
