Hi! Not many, AFAIK. To my Italian followers: If I’m forgetting any, please feel free to add more holidays.

• Ognissanti/Tutti i Santi (All Saints’ Day) – 1st November – Italians remember their dead with visits to the cemetery, usually bringing fresh flowers or candles. Because it’s a national holiday, workers usually have a day off. Ognissanti is also the holiday where people with no name day can receive small gifts or name day wishes.
• Immacolata Concezione or just L’Immacolata (Immaculate Conception) – 8th December – Italians don’t do anything exceptional on this day, though maybe special masses are celebrated. Usually when L’Immacolata falls either on a Friday or Monday, Italians talk about Il ponte dell’Immacolata (literally “the Immaculate bridge”), which is basically a long weekend. Sometimes Italians spend this holiday visiting different cities or Christmas markets in their towns. Some cities and towns will also usually hold festivals called sagre, which revolve entirely about food. Public bonfires can also be held. 
• Vigilia di Natale (Christmas eve) – 24th December – Italians usually have a pre-Christmas dinner and wait until midnight to open or exchange their gifts. Others open them on Christmas morning.
• Natale (Christmas) – 25th December – More food!
• Santo Stefano (Saint Stephen’s day) – 26th December – We hope you haven’t died two days before because.. More food!
• Vigilia di Capodanno (New Year’s eve) and Capodanno (New Year’s day) – 31st December and 1st January – More food! Also there is your entire family and every cousin you have never met! The night between the 31st and the 1st is called Notte di San Silvestro.

Towns and cities will usually organise various activities like bonfires, free museum entries, food festivals, concerts, Christmas markets, etc.

Halloween isn’t an Italian holiday and it isn’t particularly felt as such. Children might dress up and go out in their costume though. Mediaset bombards us with Halloween-themed vintage US American movies.
