I agree with abhasjha.

This would ever be an actual GMAT question, because it relies on facts concerning leap years that not everyone knows about. The fact of the matter is that most people believe that leap years occur every 4 years, but this is not the case. There are exceptions, and if you don't know the exceptions (or you have a misunderstanding of the exceptions), you'll answer the question incorrectly.

The GMAT typically doesn't ask questions that require knowledge of obscure facts.

Fair enough. The question still feels un-GMAT-like to me.

Typically, if the GMAT test-makers wanted to create a question like this, they wouldn't assume that test-takers have the requisite information. Instead, they'd provide whatever information was needed.

If this is an official GMAT question, I suspect that it appeared 2 or 3 decades ago, when most test-takers were from the US and Canada. Today, the GMAT test-makers strive to avoid any cultural bias (for more, see https://www.gmac.com/why-gmac/gmac-news/ ... -bias.aspx). Since this question hinges one's familiarity with the term "leap year," it might not be fair to students whose first language is not English.

Hi aalradadi,

While I agree with the concerns about this question, it IS essentially just a "remainder" question.

Each year (except for the Leap Year) is 365 days. Since there are 7 days/week….

1 year = 365 days = 52 weeks + 1 day

So, there's one extra day per year (and the Leap Year has 2 extra days). Each extra day "pushes" the date one day forward in the calendar.

So, in 1983, June 25 was on a Saturday
In 1984, June 25 was on a Monday (because of the Leap Year)
In 1985, June 25 was on a Tuesday
In 1986, June 25 was on a Wednesday
In 1987, June 25 was on a Thursday
