Sense: noun/1
'Dinnertime' is the most common and neutral term for the time of the evening meal in everyday English. 'Suppertime' is used in some dialects when the evening meal is a lighter, less formal affair — for example, a family that eats a large meal at midday (lunch) and a smaller meal in the evening calls it supper, not dinner. 'Dinner hour' is more formal and often refers to a fixed, scheduled period, such as a restaurant's dinner service or a break in a work schedule. In practice, many speakers use 'dinnertime' and 'suppertime' interchangeably, depending on regional custom. A useful rule: if you invite someone for 'dinner', the time is 'dinnertime'; if you invite them for 'supper', it is 'suppertime'.

Etymology
A compound word formed from 'dinner' and 'time'. 'Dinner' comes from Old French 'disner' (meaning 'to dine', originally 'to break one's fast'), and 'time' comes from Old English 'tīma' (a period or season). The compound 'dinnertime' has been in English use since at least the 18th century to refer to the habitual hour of the main evening meal.
