Etymology and history
The Latin name for June is Junius. Ovid offers multiple etymologies for the name in the Fasti, a poem about the Roman calendar. The first is that the month is named after the Roman goddess Juno, the goddess of marriage and the wife of the supreme deity Jupiter; the second is that the name comes from the Latin word iuniores, meaning "younger ones", as opposed to maiores ("elders") for which the preceding month May (Maius) may be named.
Another source claims June is named after Lucius Junius Brutus, founder of the roman Republic and ancestor of the Roman gens Junia .
In ancient Rome, the period from mid-May through mid-June was considered inauspicious for marriage. Ovid says that he consulted the Flaminica Dialis, the high priestess of Jupiter, about setting a date for his daughter's wedding, and was advised to wait till after June 15. Plutarch, however, implies that the entire month of June was more favorable for weddings than May.
Certain meteor showers take place in June. The Arietids takes place May 22 to July 2 each year, and peaks on June 7. The Beta Taurids June 5 to July 18. The June Bootids take place roughly between 26 June and 2 July each year.
