About this data

This page shows what proportion of historical-event infoboxes on Wikipedia list more than one date, a date range, or a vague term such as “circa” or “c.”. It also reports the average number of distinct date entries found per infobox when a discrepancy is present. The figures are generated by an automated script that parses the infobox template of each article, extracts all date-related fields, and flags any entry where the dates do not converge on a single calendar day. The metric highlights the inherent messiness of historical source material and illustrates the ongoing editorial work required to improve temporal precision on Wikipedia, a dimension of data quality that is not currently aggregated elsewhere.
