Sense: adjective/1
Quarterly, monthly, bimonthly, semiannual, and annual all describe how often something occurs, but at different intervals. Monthly means twelve times a year (once every four weeks), while quarterly means four times a year (once every three months). Bimonthly is ambiguous — it can mean either twice a month or once every two months, so careful writers avoid it or specify. Semiannual means twice a year, and annual means once a year. In business contexts, quarterly earnings reports are the standard for publicly traded companies, whereas monthly sales figures are used for internal tracking. For example: 'The team reviews customer data monthly, but senior management only sees a quarterly summary.' Choose the word that names the exact interval you need.

Etymology
Quarterly comes from the word quarter, meaning 'one of four equal parts'. Quarter traces back through Old French quartier to Latin quartarius ('a fourth part'), ultimately from Latin quartus ('fourth'). The suffix -ly turns the noun quarter into an adjective or adverb. The meaning 'occurring every three months' first appeared in English around the early 1400s, and by the 1600s quarterly was also used as a noun for a periodical that comes out four times a year.
