What each January date page includes
Each page starts with the observances fixed to that date, such as religious feasts, public holidays in other countries and United Nations international days. It then lists well-documented historical events and famous people born on that day.
Calculated details follow: the day of the year, the days remaining in the year, the ISO week and the zodiac sign. Dates through January 19 fall under Capricorn and dates from January 20 under Aquarius, as the January zodiac signs guide explains.
Holidays without a fixed date are flagged on every day they can land on. Martin Luther King Jr. Day, the third Monday in January, always falls between January 15 and January 21, and Lunar New Year falls in late January in some years.
