Every year, certain important days are observed at national and international levels to raise awareness about significant issues, celebrate achievements, or honour personalities and causes.

These days are often associated with specific themes, decided by the United Nations (UN) or concerned organisations.

Remembering the dates, purposes, and themes helps in both Static GK and Current Affairs sections of competitive exams.

For exams, it’s vital to remember the date, purpose, and theme of major days.
