Historical weekday (Gandhi Jayanti): Mahatma Gandhi was born on October 2, 1869. What day of the week was it?

Introduction / Context:
Determining historical weekdays can be done by known references or algorithms (e.g., Zeller’s congruence). For 19th-century Gregorian dates in British India (post-adoption), October 2, 1869 for Mahatma Gandhi is historically recorded as a Saturday. Exam settings often expect recognition of this date or correct application of weekday arithmetic from a known anchor.

Given Data / Assumptions:

• Date: 2-10-1869 (dd-mm-yyyy) in Gregorian calendar.
• We assume standard Gregorian weekday rules and no regional offset issues for the civil date.

Concept / Approach:
A quick Zeller-style computation or recalling the known commemorative weekday yields “Saturday.” While one may compute using century/month codes and leap adjustments, many aptitude keys list this as Saturday directly.

Step-by-Step Solution (outline):

Verification / Alternative check:
Independent almanacs/calendars confirm 02-Oct-1869 was Saturday.

Why Other Options Are Wrong:
Sunday/Monday/Friday do not match either algorithmic result or historical record.

Common Pitfalls:
Using Julian instead of Gregorian rules; misapplying month codes or leap-year adjustments for centuries.

Final Answer:
Saturday
