This sounds like something I might do. I am sure I am a special kind of 'date dyslexic'. I have very little concept of when things are happening. I refuse to discuss dates without my diary in front of me, because I have no concept of whether the date they gave me is weeks away or months away. If you told me now that I had to get something done by mid-November, that feels like an age away, the fact that I am on holiday for the next week wouldn't cross my mind either. I recently got undone by a calendar which had Sunday at the start of the week, visually speaking...unlike my normal Outlook calendar. It gives me a lot of anxiety, because I have some things I have to do (like authorising payroll, or filing tax returns) on certain days.
Is this a real condition, or am I just disorganised?
