The top 15 highest scoring days of the year. The top 15 days with the highest scoring diagnosis codes. Each of the codes in the table are the most enriched codes on each of the days in the date column. The black bolded dates are either holidays or are dates that surround a holiday. The orange bolded dates are associated with known rare events that clearly explain the enrichment of their codes, namely the Nisqually Earthquake on Feb 28, 2001 and the Hanukkah Eve Windstorm on Dec 15, 2006. The other dates have unusual patterns of enriched codes such as chlorine gas poisoning and tear gas poisoning, but we could not find a readily available explanation to confirm some holiday, environmental, or social event on these days. Since these events appear to have happened on a single day in a single year and look to be associated with specific events, we have masked the dates due to the unknown specificity of these events and potential for identification of individuals involved in these events
