Incremental number increase with Countif and Offset when year criteria is met

Hi everybody,
I am working on the following problem and seemed to get stuck.
My table contains the following information

#	Date	Text
20/0001	01.01.2020	Sample text
20/0002	17.01.2020	Sample text
19/0001	22.12.2019	Sample text
19/0002	28.12.2019	Sample text
20/0003	22.12.2020	Sample text

In a nutshell, I am trying to build a incrementally increasing number in Column A based on the logic that:
If a date is within the same year, increase the number in column by 1.

Thanks everyone for your help in advance.

Best regards,
Maxim

	A	B	C
1	#	Date	Text
2	20/0001	01.01.2020	Sample text
3	20/0002	17.01.2020	Sample text
4	19/0001	22.12.2019	Sample text
5	19/0002	28.12.2019	Sample text
6	20/0003	22.12.2020	Sample text

B2=IF($B2<>"",IF(SUMPRODUCT(--(RIGHT($B$2:B2,2)+0=RIGHT(B2,2)+0)),RIGHT(B2,2)&"/"&"000"&SUMPRODUCT(--(RIGHT($B$2:B2,2)+0=RIGHT(B2,2)+0)),""),"")

Copy down

=text(b2,"yy/")&text(countifs($b$1:b2,">="&date(year(b2),1,1);$b$1:b2,"<"&date(year(b2)+1,1,1)),"0000")

Thank you Carcalla,
unfortunately, it seems that this solution does not work as anticipated.

Thank you BMV,
the approach generally works, but once I hit the last row there is no subsequent reference and hence the formula returns 00/0000.

MaximH, try this
=text(b2,"yy/;;;")&text(countifs($b$1:b2,">="&date(year(b2),1,1);$b$1:b2,"<"&date(year(b2)+1,1,1)),"0000;;;")
