What format should the class schedule be in?

Question

Calendar

Hello!
You need to make a landing page for a dance school, it should have a class schedule. The customer does not care what format it will be.
The difficulty is that there will be no engine, and without intervening in the code, they themselves will not be able to change the schedule.
I suggest they embed Google calendar.
What are OTHER possible solutions?
Thank you!

Answer 1

Option 1: txt file (or any other csv for example) on the server, parse it, build a schedule, upload it via ftp
Option 2: make a miniadmin panel for adding data. You can store both in the database and in the file.
