# Letter: Tim Cook by the numbers

CEO of Apple Inc., Timothy Donald Cook, turned 60 on 11/01/2020, and I prepared a birthday gift for him:

1. The right half of Cook’s birth year, 1960, is 60.

2. Each year has 60 days after Cook’s birthday.

3. The difference of the squares of 11 and 1 equals twice 60.

4. If A = 1, B = 2 and Z = 26, the sum of the letter numbers of Timothy Donald Cook equals 204. Cook’s 60th birthday coincides with the 306th day of 2020 and interestingly, 2 x 306=3 x 204.

5. 2020 = 2 x 2x 5x 101 and 2 + 2 + 5 + 101 = 110 (Timothy).

6. Cook turns 61 in 2021. Each year has 61 days from his birthday onward.

7. Further, the reverse of 2021 is 1202 = 2 x 601 and 601 is the 110th prime number.

8. Moreover, 11^2 + 1^2 = 2 x 61.

9. Additionally, Cook’s 61st birthday is the 305th day of 2021 and 305 = 5 x 61.

10. Cook’s 62nd birthday, 11/01/2022, is special since twice 1101 is the reverse of 2022.

11. Cook’s 63rd birthday in 2023 is special since 2 x (20+23) = 86 (Tim Cook).

12. Cook’s 64th birthday in 2024 is special because 20 + 24 = 44 (Cook).

13. Furthermore, the reverse of 2024 is 4202 = 2 x 11 x 191, and 2 + 11 + 191 = 204 (Timothy Donald Cook).

14. Lastly, Cook will turn 65 on 11/01/2025 and interestingly, 6 + 5 = 11 and 6 – 5 = 1. Further, twice 6 x 5 equals 60 and 6^2 + 5^2 = 61.

Happy 60th birthday, Tim Cook!
