Hello,
I need to create a formula to include permanent (fixed) class hours in our airtable school calendar :blush: .
Classes are repeated on the same days at the same time , depending on education levels throughout the school year (from September 1, 2020 to July 5, 2021, eliminating the following school holidays:
• From Saturday October 17 to Monday November 2
• From Saturday 19 December to Monday 4 January
• From Saturday February 20 to Monday March 8
• From Saturday April 24 to Monday May 10
• From Thursday May 13 to Monday May 17
