Advice Required On Set M Qualifying Period

[Needo]

Hello & Good Morning All Board Members,
I have been going through the requirements about the qualifying period for ILR set M and got a little confused, hence requesting advice from all the senior members. Below are the details of my wife and my children visa approval and travel dates and the question which I want to know is that when they will be eligible to apply for ILR?

My Wife Entry Clearance Visa was granted on 23/10/2020
My 3 Children (My wife dependants) Entry Clearance visa was granted on 30/10/2020
They all arrived in the UK on 23/11/2020
Extension was granted on 21/11/2023 for 30 months and valid till 18/06/2026.

My confusion is that Do I need to count 5 years - 28 days from the date of visa grant (23/10/2020) or from the date of arrival in the UK (23/11/2020)?

Dear Zimba and CR7 you have helped me in the past as well so can you please advise on this?

Regards

It starts counting from date of entry to the uk.

Hi CR001
Thank you for your reply and clarification.
So in this case they will be eligible to apply from 26-10-2025.
Right?

[CR001]

Yes, if that is within 28 days before 5th anniversary of date of entry.
