add Date (dynamically: today, tomorrow) to URL-Link

Job ID: 35189685

Budget: €12 – €18 EUR

I want to easily add todays and tomorrows date into a url:

On this webpage:
https://langesundbad.wixsite.com/2022/roomshotellet

Link-URL which I thought of:
https://reservations.visbook.com/5609/search?&webProductId=[139407]&checkIn={datetime;yyyy-MM-dd}&checkOut={datetime;yyyy-MM-dd;1};

How can I do that?

The website is a room overview of a hotel. Each "URL link" will link to the corresponding room page of the hotel booking system. (webProductID will change with each room)
If I leave out the date, it will show that there is no availability as it uses todays date for checkIn and CheckOut. Therefore, I want to add todays and tomorrows date dynamically for each of the about 29 rooms so it shows a room rate.

Can you help quickly?
