Correct spelling, explanation: the word occasions is a plural of the noun occasion. It’s made by adding a popular suffix to the root. It originates from Latin occasio(n-) (meaning juncture, reason). It is easy to see that this word contains only one double consonant: -c. There is no reason why someone would add double -s to this noun. Therefore, the only correct form is occasions, not occassions.

Definition of occasions:
1. noun, events, special times, parties
2. noun, specific times when something has happened
My father bought me a computer for two occasions: my graduation and my 21st birthday.
You got so many occasions to talk to her!

Incorrect spelling, explanation: there is no need to include two double consonants in this word: -c and -s. Original Latin spelling indicates double -c only. This mistake may have occurred because of the frequent presence of double consonants in various English words. However, the only correct form is occasions, not occassions.
