If 26 November 2013 was Tuesday, then what was the day of the week on 29 November 2018?

The correct answer is Thursday.

To find the day of the week on 29 November 2018 given that 26 November 2013 was Tuesday, we can calculate the number of odd days between these two dates.

Step 1: Calculate the total number of years between 26 November 2013 and 26 November 2018.

The time duration from 26 November 2013 to 26 November 2018 is exactly 5 years.

Step 2: Determine ordinary years and leap years in this interval.

Between 26 November 2013 and 26 November 2018, we count the leap years (which include February 29):

• 2014 - Ordinary year (1 odd day)

• 2015 - Ordinary year (1 odd day)

• 2016 - Leap year (2 odd days, since Feb 2016 is included)

• 2017 - Ordinary year (1 odd day)

• 2018 - Ordinary year (1 odd day up to 26 Nov 2018)

Total odd days from 26 November 2013 to 26 November 2018:

$4 \text{ordinary years}\times 1+1 \text{leap year}\times 2=4+2=6 \text{odd days}$

Therefore, 26 November 2018 was:

Tuesday + 6 days = Monday

Step 3: Count the remaining days from 26 November 2018 to 29 November 2018.

Number of days from 26 November 2018 to 29 November 2018 = 29 - 26 = 3 days.

Step 4: Find the final day of the week.

Day on 29 November 2018 = Monday + 3 days = Thursday.
