Questions & Answers about По воскресеньям бабушка печёт вафли и подаёт к ним джем.

Why is it по воскресеньям?

This is a very common Russian pattern for repeated time expressions.

по + dative plural can mean on Sundays / on Mondays / on weekends / every Sunday, etc.

So:

• по воскресеньям = on Sundays, every Sunday
• в воскресенье = on Sunday (one Sunday, or a specific Sunday depending on context)

Here воскресеньям is the dative plural of воскресенье.

Why are печёт and подаёт in the present tense if the sentence talks about a habit?

In Russian, the present tense of imperfective verbs is often used for habitual or repeated actions.

So this sentence does not mean only what Grandma is doing right now. It means this is her usual routine:

• печёт = bakes
• подаёт = serves

Because по воскресеньям already tells you this is a repeated action, the present tense naturally gives the meaning On Sundays, Grandma bakes waffles and serves jam with them.
