The seminar in Siliguri was 3 days after Darjeeling, and Kalimpong hosted its seminar 1 day before Siliguri.

Step-by-step Explanation:

📌 Given:

• Darjeeling = 2nd March
• Siliguri = 3 days after Darjeeling
• Kalimpong = 1 day before Siliguri

📅 Step 1: Find Siliguri’s date

Darjeeling = 2 March
Add 3 days:

• 3 March (1 day)
• 4 March (2 days)
• 5 March (3 days)

👉 Siliguri = 5th March

📅 Step 2: Find Kalimpong’s date

Kalimpong = 1 day before Siliguri
👉 5 March − 1 day = 4th March

🧠 Quick Timeline:

2 March (Darjeeling) → 5 March (Siliguri) → 4 March (Kalimpong)

💡 Extra Tips:

1. Always calculate forward first, then backward
2. Use a timeline method to avoid confusion
3. Be careful with counting days (don’t skip or double count)

Final Answer:

4th March
