App Store Description

Impress your teachers, parents, and friends by telling them in mere seconds the day of the week their birthday or anniversary fell on. MentalCal includes a tutorial that explains to you the easy steps you need to follow to perform this amazing feat.

Tap the status field, that tells you whether your answer was right or wrong, twice and the tutorial will open and explain to you (based on your last answered date) what the calculation steps are to arrive at the correct day of the week for the particular date.

Are you looking for an additional challenge? Once you know the steps you can compete in three different timer modes (1 min, 3 min, and 5 min) and record your high scores on Game Center and compare your performance against others from around the world. You’ll find soon that it’s not harder than playing Sudoku or similar puzzle games.

This kind of “Mental Calendar” calculation is an official discipline at Memoriad once a year and the current world record is more than 120 dates in 1 minute, which means that some people can calculate more than 2 dates per second. How close can you get to their performance?

Learn how to calculate the day of the week for any given date between Jan 1, 1600 and Dec 31, 2099 -- exercise your brain and enjoy!
