List of Important Days in August 2025, National and International Days

Introduction

August, the eighth month of the year, is filled with important national and international days celebrated in India and across the globe. From historical anniversaries to cultural festivals, and from awareness campaigns to environmental initiatives, every week of August has significant dates to remember.

For students preparing for competitive exams, knowing these days is essential because they are often asked in General Awareness or Current Affairs sections. Teachers, activists, and the general public can also use this list to plan participation in cultural, social, or environmental campaigns.

These observances serve multiple purposes:

• Commemorating history: Remembering landmark events such as India’s Independence Day (15 August) or Quit India Movement Day (8 August).
• Promoting awareness: Highlighting global issues like World Elephant Day (12 August) or World Photography Day (19 August).
• Celebrating culture and heritage: Honouring traditions like Rakshabandhan (9 August) and Ganesh Chaturthi (26–27 August).
• Encouraging social change: Marking days such as Women’s Equality Day (26 August) and International Youth Day (12 August).
