Learn Hardcore Russian: Мой режим дня сейчас простой и удобный. - My daily routine is now simple and convenient.

The verb есть can appear in special, more contrastive or formal contexts, but in neutral modern Russian it’s normally left out in sentences like this.

Why is it мой режим дня and not something like у меня режим дня?

Both structures exist, but they are used differently.

Мой режим дня сейчас простой и удобный.
Focus: your routine itself and its qualities.
Literally: My daily routine is now simple and convenient.
У меня сейчас простой и удобный режим дня.
Focus: you as the possessor (“As for me, I have a simple and convenient routine now.”), then describes what you have.

Both are correct. The first one directly states whose routine it is (using the possessive мой), the second one uses the у меня construction (literally “by me / at me there is…”), which is often used to express possession in Russian. Here, since we talk about a specific known routine, мой режим дня is very natural.

What does режим дня literally mean, and why is дня in that form?

Режим дня literally means “regime of the day”, but idiomatically it means daily routine / daily schedule.

режим – regime, regimen, schedule (masculine noun).
дня – the genitive singular of день (day).

This structure is a common Russian pattern: Noun + (Genitive) Noun to express of X.

So:

режим дня = “regimen of (the) day” → daily regimen / daily routine.
распорядок дня is a very close synonym, more like “timetable of the day”.

Дня is in the genitive because it depends on режим in a “of the day” relationship: режим (чего?) дня.

Why are the adjectives простой and удобный in the masculine form?

Adjectives in Russian must agree with the noun in:

gender,
number,
case.

The noun here is режим:

gender: masculine,
number: singular,
case: nominative (it is the subject).

So the adjectives must also be masculine, singular, nominative:

простой (simple) – masculine, sg, nom.
удобный (convenient) – masculine, sg, nom.

If the noun changed, the adjectives would change too:

Моя работа сейчас простая и удобная.
(работа – feminine → простая, удобная)
Мои дни сейчас простые и удобные.
(дни – plural → простые, удобные)

Could we say прост and удобен instead of простой and удобный?

Yes, in principle you can use short-form adjectives:

Мой режим дня сейчас прост и удобен.

This is grammatically correct, but stylistically different:

Long forms (простой, удобный) are neutral and most common in modern speech.
Short forms (прост, удобен) can sound:
- a bit more formal, bookish, or “compact”,
- slightly more focused on the resulting state (“is simple / is convenient as a state”).

In everyday conversational Russian, простой и удобный is more natural here. The short forms are often used with stative meaning or in set expressions (e.g. я рад, он должен, он готов).

Where can сейчас go in this sentence? Is word order flexible?

Word order in Russian is more flexible than in English, and сейчас can move around:

Мой режим дня сейчас простой и удобный. (neutral)
Сейчас мой режим дня простой и удобный. (slight emphasis on “right now”)
Мой режим дня простой и удобный сейчас. (emphasis on the time aspect at the end)

All are possible, but:

The original Мой режим дня сейчас простой и удобный sounds very natural and neutral.
Putting сейчас at the beginning (Сейчас мой режим дня…) highlights the idea “as for now…” a bit more.

Why is there no comma before и удобный?

Here простой and удобный are just two homogeneous adjectives describing the same noun (режим дня), connected by и (and).

In Russian, when two single adjectives describe the same noun and are joined by и, you do not put a comma:

простой и удобный режим дня – simple and convenient daily routine.
большой и красивый дом – big and beautiful house.

You would use a comma if you had a longer list or more complex structures, for example:

Мой режим дня сейчас простой, удобный и эффективный.

What is the difference between простой and лёгкий in this context?

Both can be translated as “easy” in English sometimes, but they are not the same:

простой – simple, not complicated, straightforward.
About structure or organization:
- простой режим дня – few elements, not fussy, easy to understand and follow.
лёгкий – light, easy, not burdensome.
About effort, difficulty, weight (literal or figurative):
- лёгкий день – an easy day (not much work, not tiring).
- лёгкое задание – an easy task.

So простой режим дня focuses on the routine not being complicated;
лёгкий режим дня would suggest it doesn’t demand much effort or isn’t strict.

What exactly does удобный mean here? Is it closer to “comfortable” or “convenient”?

Удобный covers both ideas, depending on context:

“Convenient” – fits your schedule / needs well:
- удобное время – a convenient time.
- удобный режим дня – a routine that fits your life well.
“Comfortable” – physically or psychologically comfortable:
- удобное кресло – a comfortable armchair.

In удобный режим дня, the main idea is usually “convenient, suits me well, practical for me,” with a shade of comfort. So “convenient” or “comfortable” in English both work, but “convenient” is often closer.

How would this sentence change if the subject were plural, like “My daily routines are simple and convenient now”?

You’d need to make both the noun and the adjectives plural:

Мои режимы дня сейчас простые и удобные.

Changes:

Мой → Мои (masculine singular → plural).
режим дня → режимы дня (plural of режим while keeping дня in the genitive).
простой, удобный → простые, удобные (plural adjectives).

However, in real life, people rarely talk about multiple “daily routines” in Russian; they might instead say something like:

Мои дни сейчас простые и удобные. – My days are simple and convenient now.
