Questions & Answers about В понедельник я обычно читаю новости и планирую неделю.

Why is понедельник in the accusative case after the preposition в?

Because in Russian, time expressions using в (to mean “on” for days of the week) take the accusative case. So в понедельник means “on Monday.” The accusative singular of понедельник is понедельник (unchanged).

What is the difference between в понедельник and по понедельникам?

• в понедельник refers to a specific Monday (for example, this coming Monday).
• по понедельникам means “on Mondays” in general, indicating a habitual action every Monday.
  If you said по понедельникам, it would mean “I usually read the news and plan the week every Monday” in a general sense.

Why is обычно placed between the subject and the verb instead of at the beginning of the sentence?

In Russian, adverbs of frequency like обычно can appear before or after the subject (and sometimes even after the verb) without changing the core meaning. Placing обычно after the subject я emphasizes the personal habit. You could also say Обычно я читаю новости…, which puts slightly more focus on the routine aspect.

Why are читаю and планирую in the imperfective aspect here?
