Solution:
To find out the day on October 10, 2001, we need to count the number of days between May 10, 1997, and October 10, 2001.
Counting the Number of Days:
- May 10, 1997, to May 10, 2001: 4 years
- May 10, 2001, to October 10, 2001: 5 months
Calculating the Leap Years:
To calculate the number of leap years, we need to consider the number of years divisible by 4, excluding the years divisible by 100 unless they are divisible by 400.
Leap Years between 1997 and 2001:
- 1997 is not a leap year.
- 1998 is not a leap year.
- 1999 is not a leap year.
- 2000 is a leap year.
- 2001 is not a leap year.
Calculating the Total Number of Days:
To calculate the total number of days, we multiply the number of years by 365, add the number of leap years, and sum up the total months and days.
Total Number of Days:
- 4 years × 365 days/year = 1460 days
- Leap years: 1 leap year (2000)
- 5 months × 30 days/month = 150 days
- 10 days
Total = 1460 days + 1 leap year + 150 days + 10 days = 1621 days
Determining the Day:
Since May 10, 1997, was a Saturday, we need to find the remainder when 1621 days are divided by 7.
1621 ÷ 7 = 231 remainder 4
As we know that May 10, 1997, was a Saturday, the remainder 4 corresponds to the fourth day after Saturday, which is Wednesday.
Therefore, October 10, 2001, was a Wednesday.

To determine the day on October 10, 2001, given that May 10, 1997, was a Monday, we need to calculate the number of days between the two dates and find the corresponding day of the week.
- Calculation of the number of days:
First, let's calculate the number of days between May 10, 1997, and October 10, 2001.
Years:
1997 to 2001 = 5 years
Months:
May 1997 to October 1997 = 5 months
October 1997 to October 2001 = 48 months
Days:
May 10 to May 31, 1997 = 21 days
June 1997 to December 1997 = 7 months * 30 days = 210 days
January 1998 to December 2000 = 36 months * 30 days = 1080 days
January 2001 to September 2001 = 9 months * 30 days = 270 days
October 1 to October 10, 2001 = 10 days
Total days:
21 + 210 + 1080 + 270 + 10 = 1591 days
- Determining the day of the week:
To determine the day of the week, we can divide the total number of days by 7 and find the remainder. Each remainder corresponds to a specific day of the week.
1591 divided by 7 = 227 remainder 2
Since May 10, 1997, was a Monday, and there are 2 days remaining after dividing 1591 by 7, we count two days forward from Monday. Therefore, October 10, 2001, was a Friday.
Hence, the correct answer is option D) Friday.
