Magic Squares of Order 8 Representing Days and Dates of the Year 2025

This work brings dates and days of the year 2025 in terms of magic squares of order 8 for the months of May to December, 2025. It is based on reduced entries magic squares of order 8. In this work we have considered following three types of magic squares:

The first magic square is cornered magic squares, where the magic squares of orders 4 are 6 are on the left corner. In this case there two different forms of magic rectangles of orders 2×4 and 2×6. These are semi-magic rectangles as widths are equal but not the lengths.
The second magic square is single digits bordered magic square. The inner magic squares are of orders 4 and 6 respectively. Moreover, in this case, one of the diagonal give us semi-magic squares. In order to have magic square we have to use the condition T-S=2M, where S is the sum of magic square of order 4, M is the magic square of order 6 and T is the sum of the magic square of order 8.
The third magic square is double digits bordered magic square. In this case, the inner magic square is of order 4 and there are four equal sums of magic rectangles of order 2×4. The first and second magic squares represent dates of 2025 in two different forms, while the third magic square contains both these forms of representations. The magic sum in all these three cases represents the day of the year.
