Merhaba.

I´m arranging a meeting with a person.

How to ask "Which day is most suitable for you to hold our meeting?"

- Görüşmemiz için size en uygun günlerden hangisi?

- Görüşmemiz için günlerden hangisi size en iyi geliyor?

^^Are the above ok??

Thanks.

Initially I used the construction "günlerden hangisi", because once in an online course I saw this way to ask about the day of week: "Dün günlerden neydi?"... I thought that would be correct too.

But you are not asking "what day was it yesterday ? " , you are asking what day is the most suitable day for that person to hold meeting.
