Ghana gained its independence from the United Kingdom on March 6, 1957. If we assume that this year refers to 2023 (the year closest to the current date), Ghana would be 66 years old if it were to celebrate its independence this year.
Please note that this information might be outdated, and it's always best to refer to official sources or up-to-date resources to confirm the exact age of Ghana at the time of its independence celebration.
