Important days

Important days · national & international observances

Story hook

5 June 2024, 8:00 AM IST, Doordarshan News opens the day with PM Modi planting a sapling at 7 Lok Kalyan Marg under the campaign "Ek Ped Maa Ke Naam" ("A tree in your mother's name"). The occasion — World Environment Day, theme "Land Restoration, Desertification and Drought Resilience", host Saudi Arabia. By 10 AM, the Ministry of Environment press release notes that India has committed to planting 1.4 billion trees in the campaign by March 2025.

Twelve hours later, on the same calendar day, a different ministry sends out a different release. 5 June is also World Cancer Survivors Day in some calendars, and International Day for the Fight against Illegal, Unreported and Unregulated Fishing (the most awkwardly named UN observance). Three observances, one day. Multiplied across the year, the UPSC current-affairs aspirant has roughly 180 "important days" to track — birth anniversaries, theme-based UN days, India-specific observances, and a growing list of newly declared days.

Important Days is the highest-frequency Prelims topic of the calendar, drawing 3-4 questions in many recent years. The trick is not memorising 180 days. It is memorising the 40 high-yield days plus the annual theme UN observances rotate every year.

Why this matters for UPSC

UPSC Prelims has asked at least one question on important days or themes in 8 out of the last 10 years. The questions are straightforward factual ("Match List I (Days) with List II (Themes)") — easy marks if prepared, costly if not. The bucket is also a frequent interview opener — "What is the theme of this year's World Environment Day, and what does India's progress on it look like?"
