The Southern hemisphere experiences winter and summer solstice at different times than, that of the Northern hemisphere because of the following reasons:
- Southern hemisphere is tilted towards the sun on 22nd December, hence summer solstice is there in the Southern hemisphere. At that time winter solstice is in the Northern hemisphere when it is away from the sun.
- On the contrary, on 21 June the Northern hemisphere is tilted towards the Sun. Hence summer solstice is in the Northern hemisphere and winter solstice is in the Southern hemisphere.
