Hi, Dinesh. In normal procedure it looks there is no such a solution. But you can do this in the microflow. For example you want it every monday.
You can set de interval as everyday and create an object in page (or constant) in which the user defines the date. Then in the microflow you can check if it the current day equals to the date that the user defined in an object or constant. If it is then microflow is executed otherwise not.
Hi, Dinesh, you make enable "yes" and you can test locally.
