Called the “Calendar Lake” because it’s about 365 miles long & 52 miles wide, it shares its name with a country

The Final Jeopardy clue for Monday, May 25, 2026, appeared in the category “Southern Africa” and read: “Called the ‘calendar lake’ because it’s about 365 miles long & 52 miles wide, it shares its name with a country.” The clue points to one of Africa’s major lakes, known both for its size and for the memorable way its dimensions have been described.

What Is Lake Malawi?

Lake Malawi is the correct response. The clue’s phrase “calendar lake” refers to the common description of the lake as being about 365 miles long and 52 miles wide. Those numbers match the number of days and weeks in a year, giving rise to the nickname.

The lake also shares its name with the country of Malawi, which borders much of its western and southern shoreline. That part of the clue helps narrow the answer because the lake is not only a major geographic feature of Southern Africa, but also directly tied to a modern nation’s name.

The Geography of Lake Malawi

Lake Malawi is one of the largest lakes in Africa and forms part of the Great Rift Valley system. It lies between Malawi, Mozambique, and Tanzania, making it an important regional body of water in southeastern Africa.

The lake is long and narrow, which explains why its dimensions stand out in the clue. Its length and width have made the “calendar lake” nickname easy to remember, especially in geography references and quiz settings.

A Lake Known by More Than One Name

Lake Malawi has also been known historically as Lake Nyasa. That name is still used in some contexts, particularly in Tanzania, where the lake may be referred to as Lake Nyasa.

The different names reflect the lake’s position across national and cultural boundaries. However, for this clue, “Lake Malawi” is the answer because the wording specifically says the lake shares its name with a country.

Why the Lake Matters

Lake Malawi is important for transportation, fishing, tourism, and biodiversity. It is especially famous for its many species of cichlid fish, making it one of the most biologically significant freshwater lakes in the world.

For communities around its shores, the lake is more than a landmark. It supports livelihoods and serves as a central part of daily life, while also drawing visitors for its beaches, clear waters, and natural beauty.

Why This Final Jeopardy Clue Works

This clue works because it combines a memorable nickname with a clear geographic hint. The numbers 365 and 52 point to the “calendar” idea, while the phrase about sharing a name with a country leads directly to Malawi.

The correct response, Lake Malawi, fits every part of the clue. It is a major lake in Southern Africa, it is widely associated with the “calendar lake” description, and it shares its name with the country along its shore.
