Questions & Answers about Την Πέμπτη εγώ βάζω το πλυντήριο, και η αδερφή μου καθαρίζει το πάτωμα.
In Greek, days of the week used to say “on [day]” are usually put in the accusative case without a preposition.
- Η Πέμπτη = Thursday (as a subject, nominative case)
- Την Πέμπτη = on Thursday (accusative of time)
So την is the feminine accusative singular article. This is a very common pattern:
- Τη Δευτέρα = on Monday
- Την Τρίτη = on Tuesday
- Την Κυριακή = on Sunday
You could technically also say την ημέρα Πέμπτη (on the day Thursday), but in everyday speech people just say Την Πέμπτη: the accusative alone means “on Thursday”.
Greek often uses the bare accusative (no preposition) for time expressions:
- Την Πέμπτη = (on) Thursday
- Το βράδυ = (in) the evening
- Κάθε μέρα = (every) day
- Τον Ιούλιο = (in) July
So the idea of “on” is built into the case (accusative) rather than expressed with a separate preposition like English “on” or “in”.
You don’t say ✗ στην Πέμπτη for “on Thursday” in this context; just Την Πέμπτη.
