Wednesday

In many Romance languages, such as the French mercredi, Spanish miércoles or Italian mercoledì, the day's name is a calque of Latin dies Mercurii 'day of Mercury'.

Wednesday is in the middle of the common Western five-day workweek that starts on Monday and finishes on Friday.

It is a calque of Greek ἡμέρα Ἕρμου (heméra Hérmou), a term first attested, together with the system of naming the seven weekdays after the seven classical planets, in the Anthologiarum by Vettius Valens (c. AD 170).

The Latin name is reflected directly in the weekday name in most modern Romance languages: mércuris (Sardinian), mercredi (French), mercoledì (Italian), miércoles (Spanish), miercuri (Romanian), dimecres (Catalan), marcuri or mercuri (Corsican), mèrcore (Venetian).

Similarly, in Korean the word for Wednesday is 수요일; su yo il, also meaning 'water day'.

In Armenian (Չորեքշաբթի chorekshabti), Georgian (ოთხშაბათი otkhshabati), Turkish (çarşamba), and Tajik (chorshanbiyev) languages the word literally means 'four (days) from Saturday' originating from Persian (چهارشنبه cheharshanbeh).
