September 31st 1989 (31/09/89) is an incorrect date that naturally occurs in the wild at a rate of approx 1 in 45,000,000. Observing this date and noting it to be inaccurate creates a TFR minicolumn cycle somewhere in the temporal lobe, leading to immediate loss of language and imminent SUDEP. This is fatal in all cases.
Although the date occurs naturally due to accidental typo and software glitching, it often appears in malicious contexts. These malicious uses of the date account for the vast majority of fatalities.
