date with numbers: 2000+ interesting equations expressing each date of the year

In this book, Vikas Goyal brings out the beauty of numbers by linking it to dates. Dates are special; be it a birthday, or a marriage or work anniversary and if we blend the numeric logic to it, these dates become more special. For example:
If 26th September is written as 26/9, then 269 is 269th day of the year
Or if its 22nd July: 22/7
- 22/7 is the value of pi (approx.)
- 227 = 2*3*5*7 + 2 + 3 + 5 + 7 (where 2, 3, 5 and 7 are first 4 prime numbers)
- In the novel Life of Pi, the protagonist (Pi) survives 227 days
With more than 2000 expressions, the book expresses each of the 365 days of the year using basic mathematics.
Come, let's fall in love with numbers. Let's date with numbers!
