I would like to make a list of Russian names for parts of the day. For each part of the day I want to know when exactly it starts and ends, what greetings are used, adverbs like "утром" and words for meals.
I've made a short list during my studies. I'm not sure about exact time periods. Please, correct my mistakes and help me complete the list.
утро: 6AM - 12PM(?) /Food is завтрак (breakfast) / Greeting is Доброе утро! -//- утром
день: 12PM - 4PM(?) /Food is обед (lunch) / Greeting is Добрый день! -//- днём
вечер: 4PM - 10PM(?) /Food is ужин (supper) / Greeting is Добрый вечер! -//- вечером
ночь: 10PM - 4AM(?) /No food or закуска (snack) / Greeting is Спокойной ночи! -//- ночью
Can we add "рассвет"? When is it used? What about other words in between?
