Recurring, recurring , recurring

Hey! I am creating a dog walking app where I want to include a way to get weekly dog walks. When a customer creates an advert for weekly walks, I want him/her to choose a day and time where the walk repeats weekly.

How do I set this up in my database (so that the walks are automatically added at the recurring time every week) ?

Check this out.

Thank you Yongki! I will try figuring it out.
