How to remove weekends from the Chart

The weekends need not appear on Days, Weeks or Months chart even.

How to do it?

Hello Debjoy,
If you use the day scale, you can enable the skip_off_time config, then Gantt will hide the weekends:

Here is an example:

However, when the minimal scale is week or even month, there is no way to exclude the weekends. You need to implement a custom solution by creating custom time units:

Here is an example that can help you to start implementing your solution:

Thanks. Much appreciated
