Harry Styles is celebrating a festival called Rosh Hashanah. The Jewish festival began on the evening of Sept 24, and according to Jewish calendar, it marks the start of the year. The festival customs say one has to eat apples dipped in honey to bring in good luck in the new year.

Styles is known to participate in Jewish rituals. Last year, during the the time of the festival, he was reportedly seen leaving a Manhattan kosher eatery and was also seen wearing a kipah, the blue-knitted traditional cap, with his name writtern on it. Though Styles is not Jewish, as revealed by his father Des Styles on Twitter, he loves Judasim.

Director of "One Direction" movie Ben Winston said in an interview that all the 1D boys are fascinated by the traditions. They enjoy the family atmosphere.

Apart from Styles, there are many celebs and personalities who are celebrating the festival. Tthey even took to Twitter to give their best wishes to the fans on the festival. Their individual tweets can be found below.

Harry and Zach were not the only celebs who tweeted their greetings for Rosh Hashanah. Other celebs who also tweeted on the festival include Orlando Jones, Sandra Bernhard, Gail Simmons, Kerry Washington and Joshua Malina.

Rosh Hashanah urges people to ask for forgiveness and reflect on their doings in the past year. People generally celebrate the festival by indulging in sumptuous food and spending time with their family.

The festival would come to an end on Friday. People generally go to a synagogue to listen to shofar, an instrument made out of a ram's horn. The instrument is blown like a trumpet to make people think about the year gone by and to start afresh.

Tradition says people should wear white clothes or at least a new pair of clothes. Interestingly, during the festival one reflects on misdeeds and wrongdoing. However, the business of repenting reaches the hilt on Yom Kippur, which takes place on the following weekend. On Yom Kippur, a 25-hour fast is kept. The traditional way to wish on "Rosh Hashanah" is to say "Shana Tova," which means "a good and sweet new year."

Food is considered a major part of the festival, too. Apples are a vital part of the celebration as jews consider it the most beautiful fruit, according to the website reports. "Apples are mesmerizing to all the senses," explained Naomi Ross, an instructor at the Brooklyn-based Center for Kosher Culinary Arts, to Huffington Post. Other food that are customary to eat include fish, carrots, leaks, bread, new fruits and pomegranate.
