Hello @Jayron_Rosel
Let me first say that you can do this in many ways.
Method 1
If you are combining two calendars in a different calendar:
You will first need to prepare fields in Task Schedule to place data from Meeting Room Schedule and Driver Schedule.
And then, on the Meeting Room Schedule and Driver Schedule sides, you can use events like Record Create - Save Submit Success Event to send data from Meeting Room Schedule or Driver Schedule to Task Schedule upon successful record saves.
Ref.:
- API Doc: Save Submit Success Event -
app.record.create.submit.success - Similar Forum post: Copy data from another app - General - Kintone Developer Forum
Method 2
Or you can try to display two calendars in a different app using Custom View. Similar to the one you can do in a dashboard of a portal.

I hope this helps.
