Hi @shekhar,
you wont (I just tried) be able to do it in a simple way within the current Mautic functionalities within campaigns. But you would be able to call a webhook. So you could send for example the contact ID to the webhook, have this external script check for the weekday and use the Mautic API to update a field in the contact identified by the ID you just sent. This field could contain the information that is needed to put this contact into a specific weekday (say Monday) segment. Then you could use this segment as a starting point for another campaign.
You would need to create the external script that would be your webhook’s endpoint, but this would make it possible to achieve something like this.
In a different thread, some time ago @joeyk explained it: Mautic campaign Webhooks - #6 by joeyk
