Etymology

The Greek letter Zeta with an abbreviation stroke, for Ζεύς (Zeús), the Greek equivalent to the Roman god Jupiter. The form changed from Classical and early Medieval ⟨Ƶ⟩ to one with a more salient cross, ⟨♃⟩, in the 15th–16th century, at about the time that Christian crosses were added to ⟨☿⟩, ⟨♀⟩ and ⟨♄⟩, and so may have had a similar motivation.

Use of ♃ for Thursday, near the bottom of the calendar dial of this 16th-century clock-calendar.
