Julian Date Calendars
AAVSO produced JD Calendars give the last four digits of the Julian Day for each day of every month for a year. The months January-June are on one page while July–December are on the second page. For the complete JD, add 2,450,000 (or 2,460,000 after February 23, 2023) to the four digit value given in the calendar for the Astronomical Day of your observation.
