ILR from spouse visa/when to apply

[turkishh]

Hi guys, I am a bit confused here trying to calculate my visa dates.

I came to the UK with Tier5 visa on 04/12/2016.
I got the first Spouse/Leave to Remain Visa on 16/09/2016. (They gave me 2 years, 6 months, 28 days)
I extended this visa for the second Spouse/Leave to Remain Visa on 04.04.2019 expires 30.10.2021
(They gave me 2 years, 6 months, 28 days again)

My question is when can I apply for Indefinite Leave to Remain? I know I need to complete 5 years. Do I need to calculate from the date I first came here with Tier 5? or Do I need to calculate the beginning of my spouse visa? If so, my first spouse visa was on 16.09.2016, when I add 5 years on, it comes to 16.09.2021. So can I apply 28 days before this date? If I can, I will be applying 28 days before reaching 60 months with Spouse Visa? So I can apply after 16.08.2021 any time for ILR?

Would it be too early as my BRP expires a bit late than that date? The date is on Brp OR duration of months are important?

I know you guys are really good at these things. I am sure someone like me applied before or can help me?

Thanks in advance!

It counts from the date your first spouse visa was ISSUED.

Thanks a lot for your reply. so I can apply after 19.08.2021 for ILR?

I know it's annoying to repeat the same question but It is just good to hear from someone else. Then I can be sure

If that is within 28 days before the 5th anniversary of your initial spouse visa issue date, then yes.
