I'm trying really hard not to remember dates anymore either. Or numbers. My brother died on the 16th of the month, and for a few months after his death I was feeling upset everytime I realized it was the 16th. My actual trauma occurred on the 4th, and I couldn't even say the word "four" for a few years, and January was always a horrible month for me. January 4th shortens to 1-4, so I started associating the number 14 with my trauma too, even though nothing happened on that day.
