Read the text and answer the questions below. When did they visited Yogya Kraton?

    On Wednesday, my student and I went to Yogyakarta. We stayed at Dirgahayu Hotel which is not far from Malioboro.
    On Thursday, we visited the temples in Prambanan. There are three big temples, the Brahmana, Syiwa, and Wisnu temples. They are really amazing. We visited only Brahmana and Syiwa temples, because Wisnu temple is being renovated.
    On Friday morning we went to Yogya Kraton. We spent about two hours there. We were lucky because we were led by a smart and friendly guide. Then we continued our journey to Borobodur. We arrived there at four p,m. At 5 p.m. we heard the announcement that Borobudur gate would be closed.
    In the evening we left for Jakarta by wisata bus.
