I have a field where people can enter a birthdate. I want that to show up on a calendar view in Airtable. Unless the year is the current year, it's not showing up on the calendar. I tried using a formula field but then I can't get the formula field to show up on the calendar. How do I get it so people can enter the actual birthday say 2-6-68 but have it show up on a Feb 2024 calendar view in airtable? Also, do I need to do anything different so that in 2025 it would show up in Feb calendar view?
