Hey, I am trying to figure out where I have to add the "s" to a weekday. I have the following sentences, all events are recurring, i.e. happen every week. Is this correct?

In order for everyone in the US to receive the weekly team call agenda on Thursdays and not just on Fridays in the morning I have made changes to the updating schedule that will come into effect next week.

Please make all your changes by Wednesday night because I will start sending the agenda to X for the his final review on Thursdays

Thanks a lot
