Questions & Answers about शनिवार को फिल्म, रविवार को पार्क।
This is a very common kind of elliptical Hindi expression: words that are easy to guess are simply left out.
A fuller version could be something like:
- शनिवार को फिल्म देखेंगे, रविवार को पार्क जाएँगे।
- शनिवार को फिल्म, रविवार को पार्क चलेंगे।
But in short, list-like speech, Hindi often drops the verb when the meaning is obvious from context. It feels a bit like English notes such as:
- Saturday: movie. Sunday: park.
So yes, it is natural Hindi, especially in casual speech, planning, captions, or short messages.
Here को marks time, especially with days and dates. In this sentence:
- शनिवार को = on Saturday
- रविवार को = on Sunday
This use of को is very common with specific points in time:
- सोमवार को = on Monday
- शाम को = in the evening
- एक बजे को is not natural, but एक बजे works without को
So in this sentence, को is not an object marker. It is marking the day as the time when something happens.
