This date helps determine a person's age and can influence various aspects of life, such as eligibility for certain activities or benefits. In many cultures, the Date of Birth is celebrated annually as a birthday, often marked by parties or special traditions. It is also used in official documents, such as passports and birth certificates, to verify a person's identity and age.
