Sir, the right person to answer your query is someone in C.E department of fpsc
for instance, assistant director (competitive examinations) might be able to guide you on this

I can also try to calculate the time frme of your job. You would like to sit in css-2025, right?

Your 2 years on this job will be on 1st August 2024, which means you will meet he two years age relaxation criteria

However, there is one thing, you need to get checked: Whether the two-year age relaxation is for Federal employees only or does it also applies to provincial government employees.

Regards

p.s. Also, note that these are all based on existing rules

I am copying the relevant rule about 2-year age relaxation from page 3 of css rules - 2019:

"(f) in-service Government servants, armed forces personnel, contract employees, including the Government servants of Azad Jammu and Kashmir, who possess a minimum of two years continuous Government service as on the cut-off date subject to production of departmental permission certificate from the competent authority as set out by the Commission from time to time. Employees of nationalized banks, State Bank of Pakistan, Water and Power Development Authority, regulatory authorities, autonomous bodies and other semi-autonomous bodies are not entitled to the age-relaxation under these rules:
Provided that period of extraordinary leave (EOL) shall not be considered as period spent on duty under Fundamental Rule-9(6) for grant of age-relaxation under these rules."
