31January

31 January is the 31st day of January, the final day of the month in the Gregorian calendar. Because January has 31 days in every year, 31 January always marks the end of January and the day before 1 February.

The name January derives from Janus, the Roman god of beginnings and endings, reflecting the month’s association with transitions. In most date formats, the date is written as 31 January (day-month-year) in many parts of the world, while others use January 31 (month-day-year).

Religious and cultural observances on 31 January include the feast day of Saint John Bosco in the Catholic Church, who is commemorated on January 31. The date is primarily a calendar marker used in scheduling, history timelines, and annual planning.

In historical records, various events have occurred on this day across different years, making it a common reference point for anniversaries, though no single event universally defines the date.
