Editing Calends (section)

== Expressions ==
The calends was a feature of the [[Roman calendar]], but it was not included in the [[ancient Greek calendars|Greek calendar]]. Consequently, to postpone something ''ad Kalendas Graecas'' ("until the [[Greek calends]]") was a colloquial expression for postponing something forever. This phrase survived for many centuries in Greek ({{langx|grc|εἰς τὰς ἑλληνικὰς καλένδας}}) and in the [[Romance languages]] ({{langx|es|hasta las calendas griegas}}; {{langx|it|alle calende greche}}; {{langx|fr|aux calendes grecques}}; {{langx|ro|la calendele grecești}}; {{langx|pt|às calendas gregas}} ; etc.).

The Latin term is traditionally written with initial ''K'': this is a relic of traditional Latin orthography, which wrote ''K'' (instead of ''C'' or ''Q'') before the vowel ''A''. Later, most Latin words adopted ''C'', instead. It is sometimes claimed that the kalends was frequently used in formal or high-register contexts, and that that is why it retained its traditional spelling, but there seems to be no source for this.
