How does the length of daytime and night time affects the seasons?

The length of daylight or nighttime hours does not affect the seasons, but the seasons affect the length of daytime and nighttime hours. During the summer, the earth is tilted more toward the sun, resulting in longer daytime hours. During the winter months, the earth is tilted away from the sun, resulting in shorter days and longer nights.


What is the significance of June 21?

There is no single answer to that. Different parts of the northern hemisphere will have different lengths of daylight on the 21st of June. The further north of the equator you go, the more hours of daylight there will be, with there being about 12 hours at the equator and 24 hours at the north pole. So you need to know exactly where in the northern hemisphere you are before the question can be answered.
