Learn Hardcore Russian: В расписании моего дня есть время для перерыва. - In my daily schedule, there is time for a break.

It translates to "In the schedule of my day, there is time for a break." The sentence indicates that within the speaker’s day, they have set aside time specifically for a break.

Why is the word есть used in this sentence when Russian often drops the verb “to be” in the present tense?

In existential constructions like this one, есть is used to explicitly express existence—in this case, that “time for a break” exists within the schedule. While Russian usually omits the present tense of “быть” (to be) in simple statements (like “Он студент”), using есть here clarifies that something is present or available.

What is the function of the phrase моего дня, and why is it in the genitive case?

The phrase моего дня literally means "of my day" and modifies расписании to indicate whose schedule is being referenced. The genitive case is used to express possession or association, showing that the schedule belongs to or is part of the speaker’s day.

Why does перерыва appear in the genitive case in the phrase для перерыва?

The preposition для always requires the following noun to be in the genitive case. Thus, перерыв (break) becomes перерыва, meaning "for a break."
