A moment for you

How the reading works

An algebraic 4 × 4 construction whose first row is [day, month, first two year digits, last two year digits]. The other twelve cells balance these values to preserve ten equal sums: four rows, four columns and two diagonals.

Enter a date and create a grid of 16 numbers. Explore how its rows, columns and main diagonals all have the same sum.

What it is for

Turn a meaningful date into a number composition you can explore and keep. It might be a birth date, anniversary or a day to remember. Its special feature is the structure of its sums; the date personalizes the grid without assigning personality traits or powers.

How to use it

Enter a valid date from year 1000 to 9999 and create the square. Use the row, column or diagonal controls: their four numbers light up and the full addition appears. The first row keeps the date in four parts, even when numbers repeat.

Reading your result

The common sum is the total of the date’s four parts. This variant permits negatives, zeros and repeated values; they all count in the sums. Shifted diagonals need not match. You can download the image and save the square with its ten checks.
