The Chinese zodiac is a classification scheme based on the lunar calendar that assigns an animal and its reputed attributes to each year in a repeating 12-year cycle. The 12 year cycle is an approximation to the 11.85-year orbital period of Jupiter. Originating from China, the zodiac and its variations remain popular in many East Asian and Southeast Asian countries, such as Japan, South Korea, Vietnam, Cambodia, and Thailand.

Historian Peter Berresford Ellis argues that although there is evidence of the development of Irish astrology from the 7th Century AD onwards, anything earlier is left to conjecture based on continental Celtic artifacts like the Coligny calendar.

Hellenistic astrology is a tradition of horoscopic astrology that was developed and practiced in the late Hellenistic period in and around the Mediterranean region, especially in Egypt. The texts and technical terminology of this tradition of astrology were largely written in Greek. The tradition originated sometime around the late 2nd or early 1st century BCE, and then was practiced until the 6th or 7th century CE. This type of astrology is commonly referred to as "Hellenistic astrology" because it was developed in the late Hellenistic period, although it continued to be practiced for several centuries after the end of what historians usually classify as the Hellenistic era.
