I have been collecting information from various resources regarding the special properties being associated with today's date.
It's already 5th June today. So, today I will share properties from the dates (numbers) 1 to 5.
In future I would prefer to post day wise.
In case you also wish to share something interesting kindly do it.
Any suggestions are also welcome.

prime number that ends in 5.
2. there are 5 Platonic solids
3. A
five-sided polygon (pentagon) has 5 diagonals. This is the only shape for which
the number of sides and diagonals is the same
4. 5 is a Fibonacci Number.

5. A 4 x 4 square has an area equal to its
perimeter.
6. The atomic number of beryllium.
7. Using four 4's and any operations, try to write
equations that have the integers from 1 to 100 as the answer (see example
below):
1 = 44/44
2 = 4/4 + 4/4
3 = (4 + 4 + 4)/4
4 = 4(4 - 4) + 4, etc...

4.
Three is the number of dimensions that humans can
perceive. Humans perceive the universe to have three spatial dimensions
5. There are
three geometric constructions you cannot build using just a ruler and
compasses: 1. You cannot trisect - divide into three equal parts - a given
angle; 2. Double a cube; and 3. Square a circle. (Geometric Problems
of Antiquity).
6. Three non-collinear points

9. Three is the atomic
number of lithium.

a polygon with
three edges and
three vertices,

construction, engineering and design.
