Explanation:

- To find out the day of the week for 2 March 2006, compared to 2 March 2022 (a Wednesday), you need to calculate the difference in days.

- The period from 2 March 2006 to 2 March 2022 includes 16 years.

- Every year typically adds one day to the week, but leap years add an extra day (2 days in total).

- From 2006 to 2022, leap years are 2008, 2012, and 2016, plus 2020 – totaling 4 leap years.

- Total extra days from leap years = 4 days, and including normal years = 12 days.

- Total extra days = 16 days.

- Starting from Wednesday, move backward 16 days in the week.

- 16 days back from Wednesday is Thursday. ??
