Need a snow day?
All you need for this spell is one black candle.
Light the candle the night before the day you want the snowday.
Then recite the following incantation three times:
I call upon thee,
make tomorrow a snowday,
so mote it be.
NOTE: This spell is best used to catch up on work, or something important, and not to laze around or it will either not work, or backfire. Use a new candle every time.
