STM32L452RE hardware calendar - year range ?

Hi,

I’m trying to confirm the supported year range for the built-in hardware calendar in the STM32L452RE.

Since the RTC year register is two digits (00–99), does this mean the calendar supports dates from the year 2000 to 2099?

I’d appreciate it if anyone could clarify up to which date the RTC can correctly calculate.

Thanks,
