World Homeopathy Day is observed globally on which date to mark the birth anniversary of Dr Samuel Hahnemann?

Introduction / Context:
This question relates to World Homeopathy Day, an observance that recognises the contribution of homeopathy to health care and commemorates the birth of Dr Samuel Hahnemann, the founder of the homeopathic system of medicine. The date is important for medical and alternative medicine related general knowledge.

Given Data / Assumptions:

• The observance is World Homeopathy Day.
• It is tied to the birth anniversary of Dr Samuel Hahnemann.
• The options give several consecutive dates in April.

Concept / Approach:
The concept is to link an observance with the birth date of a key figure. The approach:

• Recall that World Homeopathy Day is celebrated on 10th April, the birth date of Dr Hahnemann.
• Confirm that other dates around it do not match this birth anniversary.
• Select 10th April from the provided options.

Step-by-Step Solution:
Step 1: Understand that the question connects an observance with the founder of homeopathy. Step 2: Remember that Dr Samuel Hahnemann was born on 10th April. Step 3: Recognise that World Homeopathy Day is celebrated globally on this same date to honour his contribution. Step 4: Examine the options and identify 10th April among them. Step 5: Confirm that 9th, 11th, 12th and 13th April are not correct for this observance.

Verification / Alternative check:
Verification can be found in health ministry press releases, homeopathy council announcements and general knowledge references. These clearly state that World Homeopathy Day is observed on 10th April every year, marking the birth of Dr Samuel Hahnemann. Homeopathy conferences, awareness programmes and academic events are regularly scheduled on 10th April, reinforcing the association between this date and the observance.

Why Other Options Are Wrong:
13th April: Associated in India with other events such as Baisakhi and Jallianwala Bagh remembrance, not World Homeopathy Day. 12th April: Not the birth date of Dr Hahnemann and not used for this observance. 11th April: Close in time but incorrect for this particular day. 9th April: One day before the correct date, used as a distractor for those who misremember the exact day.

Common Pitfalls:
A common pitfall is to mix up various April dates that are linked with different health or historical events and to guess a day near the correct one. Another issue is not linking the observance directly with the person being honoured. A simple memory aid is to remember “10 April – Hahnemann – World Homeopathy Day” as a trio, so that both the name and the date reinforce each other in your mind.

Final Answer:
World Homeopathy Day is observed globally on 10th April.
