I want to know, when is lunchtime and when is time for dinner?
I think, that lunchtime is around 12 o'clock. Thanks!

dinner is sometimes the same time as lunchtime...

And is there an other name for eating in the evening than dinner?

Or, could it be: "They eat dinner at twelve o'clock." (in the evening)? What means the Chinese sentence? Who can help?

the Chinese sentence says at night

Does "dinner" here mean the meal you eat at noon time or a little after that? :)

@Eldad: Now I think in the late evening.

And now some sentences have to be changed, isn't it?

@Shishir: ¡Muchas gracias Shishir!

@Espi, indeed :)
Manche Sätze müssen geändert werden.

In the Spanish sentence #628642, Dejo says that it can mean both...

In many English speaking regions, "dinner" is midday meal. The evening's meal is "supper".

I'll add another variant for the meal which is eaten in midday.
