Calendar – Day of week: P. V. Narasimha Rao was elected party leader on 29 May 1991. What was the day of the week?

Introduction / Context:
This is a routine day-of-week determination problem for a given historical date using standard calendar computations.

Given Data / Assumptions:

• Date: 29 May 1991.
• Gregorian calendar rules.

Concept / Approach:
Compute the weekday using Doomsday/Zeller-like methods or verified anchor references for 1991, then apply month/day offsets to reach May 29.

Step-by-Step Solution:
1) Establish 1991’s reference weekday (e.g., Doomsday falls on Thursday).2) Use May’s doomsday (in non-leap years, 5/9 is a doomsday) and offset to 5/29.3) The arithmetic yields Wednesday for 29 May 1991.

Verification / Alternative check:
Perpetual calendars confirm that 29-05-1991 was Wednesday.

Why Other Options Are Wrong:
Tuesday, Friday, Sunday → do not align with the computed weekday.

Common Pitfalls:
Misusing leap-year adjustments or month-specific reference days.

Final Answer:
Wednesday
