Synonym discussion
Sense: adverb/1
All four point to an open, unfixed moment, but they sit at different registers. 'Anytime' is the everyday, friendly choice — common in invitations like 'call anytime'. 'Whenever' adds a stronger 'no matter when' flavour and usually leads into a clause: 'whenever you're ready'. 'At any time' is the formal, written form, used in notices, contracts, and announcements ('passengers may board at any time'). The two-word 'any time' is a noun phrase and works better with prepositions or deadlines, as in 'I don't have any time' or 'finish it by any time before noon'. Use 'anytime' in casual chat, 'whenever' when emphasising freedom of choice, and 'at any time' when the tone is official.

Etymology
A modern American compound formed by joining 'any' (Old English 'ænig', meaning 'one of a kind') with 'time' (Old English 'tīma', meaning 'a stretch or point of time'). The two-word phrase 'any time' has been used in English since the Middle Ages, but the closed one-word adverb 'anytime' became popular in everyday American writing during the early twentieth century and has since spread into informal British use as well.
