Answer:

Introduction
India got independence on a significant day of the week, and its 100 years of independence will also fall on an important day of the week. Let's explore the answer in detail.

Independence Day of India
India got independence on August 15, 1947. It was a Friday. This day is celebrated as Independence Day every year with great enthusiasm and patriotism.

100 Years of Independence
India will complete 100 years of independence on August 15, 2047. As per the question, we need to find out which day of the week it will be.

Calculation
Given that the year 2023 started with a Sunday, we can calculate the day of the week for any future year. Here's how we can do it:
- 2023 is a non-leap year, so it has 365 days.
- One week has seven days, so 365 divided by 7 gives a remainder of 1. This means that if a year starts on a Sunday, the next year will start on a Monday.
- We can apply this logic to find out the day of the week for any future year. For example:
- 2024 is a leap year, so it has 366 days. 366 divided by 7 gives a remainder of 2. This means that if a year starts on a Monday, the next year will start on a Wednesday.
- Similarly, 2025 will start on a Thursday, 2026 will start on a Friday, and so on.
- We can repeat this process until we reach 2047, which is the year of India's 100th independence day.

Answer
- 2023 starts on a Sunday.
- 2024 starts on a Monday.
- 2025 starts on a Thursday.

- 2029 starts on a Tuesday.
- 2030 starts on a Wednesday.
- 2031 starts on a Thursday.
- 2032 starts on a Saturday.
- 2033 starts on a Sunday.
- 2034 starts on a Monday.
- 2035 starts on a Tuesday.
- 2036 starts on a Wednesday.
- 2037 starts on a Friday.
- 2038 starts on a Saturday.
- 2039 starts on a Sunday.
- 2040 starts on a Tuesday.
- 2041 starts on a Wednesday.
- 2042 starts on a Thursday.
- 2043 starts on a Friday.
- 2044 starts on a Sunday.
- 2045 starts on a Monday.
- 2046 starts on a Tuesday.
- 2047 starts on a Thursday.
