How many days are there from 2 January 1993 to 15 March 1993 (inclusive of both dates)?

Introduction / Context:When counting days between two calendar dates, first decide whether the interval is inclusive or exclusive. Inclusive counting adds both endpoints; exclusive counting omits one or both ends. Here, we use inclusive counting as is common in aptitude calendars unless specified otherwise.

Given Data / Assumptions:

• Year 1993 is a common (non-leap) year; February has 28 days.
• Start date = 2 Jan 1993; End date = 15 Mar 1993.
• We count inclusively (both 2 Jan and 15 Mar included).

Concept / Approach:Sum days in each segment: from 2 Jan to 31 Jan, full February, and 1–15 March. Use month lengths for a common year.

Step-by-Step Solution:

Verification / Alternative check:Exclusive-of-start (i.e., counting from 3 Jan) would yield 72; since the problem intends inclusive, 73 is consistent with listed options and standard convention.

Why Other Options Are Wrong:72 corresponds to excluding one endpoint; 74 and 71 miscount month lengths or inclusivity.

Common Pitfalls:Forgetting inclusive counting or miscounting February as 29 days in a non-leap year.

Final Answer:73.
