Citizenship absence calculation

Hi
I'm Gen tier 2 visa holder since 2016 and end of this year will be eligible to apply ILR.
I have a question about Citizenship absence calculation.

To apply Citizenship, we should not be out of UK 450 days in continuous 5 years of completion and 90 days in the year ( 6th year ) which we'll be eligible to apply Citizenship.

So, my question that 450 days and that 90 days, are they going to be calculated separately ?
I meant, i am BRP holder since 2016, so 450 days will be covered bettween 2016 - 2021 and 90 days will be calculated in 2022 separately ?
2022 absences will not be counted on those 450 days, right ?

Regards
Cihan

Citizenship is based on the 5 years immediately preceding the date of application and not 6 years.

So, my question that 450 days and that 90 days, are they going to be calculated separately ?

No more than 450 days in the whole 5 years immediately preceding the date of application and no more than 90 days (part of the 450 too) in the 12 months immediately preceding the date of application.

If you apply for citizenship in 2022, the only relevant period is 2017 to 2022, the 5 years immediately preceding the date of application. Your TOTAL absence in the 5 yeas cannot be more than 450 days and the last 12 months not more than 90 days (still part of the 450 days).
