Normal sudoku rules apply. A white rectangle (white dot in Sudokupad) is given if and only if the two adjacent digits are consecutive.
Olivia and Ingrid are time-traveling friends who came back from the future to create this sudoku. Within it, they both hid a code. Each code is 9 digits long. Ingrid placed her code in one of the 2 long diagonals, read from left to right. Olivia hid her code in one of the 9 3x3 boxes. The first and last digit of each code sum to the first letter of their name. I=9, O=15. The middle seven digits contain their future birthdays in this form DD/M/YYYY. Both are born on the last day of the month, and Ingrid's birthyear is more than double Olivia's birthyear.
Solution code: Ingrid's code and Olivia's code

Loved the experience from start to finish. Cute story! Unique break-in, smooth logic, and I'm a sucker for if and only if clues. Looking forward to your next puzzles!
