Hi @Manager_DGP - the short answer is “you can’t” - unlike, say, Excel, Airtable won’t do a lookup between two unrelated tables so you have to make the explicit link between the two to get this to happen. Here’s a couple of options:
Here’s your Events table:

You could have a “fully explicit” calendar, i.e. each day of the year and link the event to the day in the calendar:

You could group this by week to get more of a week view:

Or, have as “week starting” calendar, as you have in your post and link the event to the week:

The advantage of the first option is that when you make the link you’re explicitly matching the same date in each table; with the second, you’re matching a date with the week it falls into - not exactly hard, but possible more prone to error.
Hope this helps
