I don't normally take my holiday in midsummer.我一般不在仲夏休假。
a midsummer evening仲夏之夜
the summer solstice, the day of the year on which it is light for the longest period of time (21 June in northern parts of the world, 22 December in southern parts of the world)夏至
It's midsummer sometime this week, isn't it?夏至是在本周的某一天,是吗?
