Halloween is celebrated in many countries around the world, although the specific form of the holiday varies greatly from one country to the next. Here are some countries that celebrate Halloween:

• Mexico: Halloween is celebrated in Mexico as "Dia de los Muertos" or "Day of the Dead," which is a three-day celebration that begins on October 31st and ends on November 2nd. During this time, families gather to remember and honor their deceased loved ones.

• England: Halloween is becoming increasingly popular in England, particularly among children. However, it can often be overshadowed by another, much larger event: Guy Fawkes Day.

• Italy: In some regions of Italy, people fashion lanterns by placing candles in pumpkins, and eat a meal near the gravesites of loved ones.

• Guatemala: Halloween is a new holiday in Guatemala, and it is celebrated by adults who don costumes and head to parties and clubs.

• Ireland: Halloween is a big deal in Ireland, where the celebration began in the first place. Halloween as it is known today originated from the ancient festival of Samhain, which celebrated the beginning of winter in pagan Ireland more than 2,000 years ago.

• Australia: Halloween is catching on in Australia, where houses hang an orange balloon outside to signal they have lollipops for trick-or-treaters.

• Brazil: Brazil has large Halloween celebrations, particularly in Rio de Janeiro, where costumes and partying are abundant.

• Chile: Chile celebrates Halloween very similarly to the U.S., but extends their celebrations beyond mere trick-or-treating to include cultural, culinary, and other large festival entertainment options such as beer festivals, film screenings, and art exhibits.

• South Africa: The tradition of Halloween is not particularly a candy-themed holiday in South Africa. The art of trick-or-treating is slowly gaining momentum in the different communities, and Halloween is celebrated much the same as in the United States.

These are just a few examples of countries that celebrate Halloween. While the holiday is catching on in many places around the world, there are still many countries that do not celebrate it or have their own traditions for honoring the dead.
