Earth Day, dedicated to environmental protection awareness, is celebrated every year on which date?

Introduction / Context:
This question focuses on Earth Day, one of the most widely recognised environmental observances worldwide. It is important in topics such as ecology, climate change and sustainable development, so its date often appears in general knowledge and environmental studies sections of exams.

Given Data / Assumptions:

• The observance is Earth Day.
• It is celebrated annually on a fixed date in April.
• The options include different dates, plus a generic option “None of these” and another important environmental date.

Concept / Approach:
Earth Day is a global event that promotes awareness and action for protecting the environment. The approach to answer the question is:

• Recall that Earth Day is observed on 22nd April every year.
• Recognise that 5th June is connected with World Environment Day, which is different but related.
• Dismiss “None of these” once you see that 22nd April is listed among the options.

Step-by-Step Solution:
Step 1: Identify that the question refers specifically to Earth Day, not World Environment Day or other ecological observances. Step 2: Recall that Earth Day is celebrated on 22nd April each year, with events, campaigns and educational programmes worldwide. Step 3: Examine the options and find 22nd April. Step 4: Note that 1st January and 30th April are not associated with this observance. Step 5: Recognise that 5th June belongs to World Environment Day, which is a separate UN supported event. Step 6: Therefore, “None of these” is incorrect because the correct date is actually listed.

Verification / Alternative check:
Verification is easy through school textbooks, environmental awareness campaigns and global media coverage. Every year, news reports, websites and social media highlight Earth Day on 22nd April, often showcasing clean up drives, tree planting and climate related discussions. Many educational institutions specifically schedule their environment themed activities on this date, confirming the association.

Why Other Options Are Wrong:
1st January: New Year's Day, not related to Earth Day. 30th April: Not designated as Earth Day; it is included as a distractor late in the month. None of these: Incorrect because the correct date, 22nd April, actually appears in the list. 5th June: This is the date for World Environment Day, which is a separate but related global observance supporting environmental protection.

Common Pitfalls:
A frequent mistake is to confuse Earth Day with World Environment Day and to choose 5th June instead of 22nd April. Another error is to assume that the presence of “None of these” means the correct date is absent, without carefully checking the other options. To avoid this, always recall that Earth Day is in April, while World Environment Day is in June, and double check all given options before deciding.

Final Answer:
Earth Day is celebrated every year on 22nd April.
