If you mean Minecraft Classic, this is not possible. Minecraft classic is only meant for building, not survival. If you want to have survival, you'd have to buy the full version.

to change from day to night in minecraft without mods you have to wait until the sun goes down. to get from night to day you can right click a bed to sleep.
what you do is press escape or Esc on your keyboard that will make minecraft pause. Then go to options the change to difficulty to hard wait for night then wait for something to kill you. After you respawn change it back to easy or peaceful or what you were playing on.
In Minecraft, there is a total of 20 minutes in a day (including night). A Minecraft day (sunlight) lasts 10 minutes, and a Minecraft night lasts 10 minutes. Therefore, a Minecraft day in total lasts about 1,200 seconds, and during the day and night about 600 seconds. I hope this helped!
