Appendix H: Spring Phenomena 25 BCE to 38 CE – from Reckoning of Time
The first table below gives the Julian calendar dates and Greenwich times of the astronomical vernal equinox for the years 25 BCE to 38 CE inclusive. The second table gives, for these years, the Julian calendar dates and Greenwich times of the astronomical Full Moons which occurred on or after the date of the equinox, and the dates and times of the astronomical New Moons on or preceding, and after, the date of the equinox. The days of the week are given for the equinoxes and the Full Moons, from which the days of the week may readily be found for the New Moons.
The times given in the tables are accurate to within two or three hours for 25 to 5 BCE, and one or two hours for 4 BCE to 38 CE.
