Dove si mettono le preposizioni di tempo in inglese?

Hello! There are three prepositions of time: at, on, in. We use AT when we talk about specific times or hours: at 5 o'clock. We use ON when we talk about days and dates (it's a kind of a less specific in comparison with the previous one): on Monday, on my Birthday. And finally, we use IN when we talk about weeks, months, years, decades, centuries: in 2020. Shortly, it depends on how specific the period of time you talk about. Some exceptions: in the morning, in the afternoon, in the evening BUT at night, in 5 minutes, At/On the weekend

Ciao se intendi i complementi di tempo, questi vanno generalmente in fondo alla frase secondo la regola MANNER PLACE TIME. Gli avverbi invece seguono un'altra logica, precedendo di solito il verbo principale. E.g. I often go to the cinema. Nulla vieta però, per dare enfasi al discorso di spostarne la posizione all'inizio della frase.
