Creating a script that use a database or array

[khalil]

It's very unlikely that the scheduled script will miss its execution. It would be better to use a formula and create scheduler events for the current day one per day.
Have you seen this Python script? Should be quite easy to rewrite it into Lua:

thank you admin for your time,
I see such websites that used formula but in our region they used a table while there are several minutes different between the table and the formula (not in all days and not in all prays). So I will use the table because its the most reliable right now.
