Stay on guard! You will surely be the victim of a prank during April Fools' Day, so be extra-careful of pranksters looming around you.

April Fools' Day is a light-hearted comedic day of cheers, practical jokes, and hoaxes. It has been observed for centuries although its origins still remain unclear. It has been suggested that in ancient Roman and Hindu cultures, the day originally marked New Year’s Day. In 1582, Pope Gregory XIII issued the Gregorian calendar which moved New Year’s Day from April 1st to January 1st. It is believed that those who continued to celebrate New Year’s Day on April 1st were referred to as fools, leading to the concept of April 1st representing All Fools’ Day. It has also been suggested that April Fools' Day is related to the vernal equinox, the beginning of spring, when Mother Nature plays sudden weather tricks on people.

The custom of April Fools' was brought from Britain to the US centuries ago. Both kids and adults in North America and in Europe have developed traditional customs to celebrate the day. These typically include fooling another person and yelling April fools.

• Traditionally, pranksters shout April Fool as they reveal the joke. In the United Kingdom, jokes can only be played until midday. If someone plays a joke after midday, then they are the April Fool. In Ireland, tradition was to deliver an important letter to a person, who would then deliver the letter to another person, and so on. Once finally opened, the letter would say send the fool further.

• One of the best ways to fool someone on April Fools' Day is to call them first thing in the morning. This way, they are less likely to realize that it is April Fools' Day.

For many churches, Good Friday is the final service of Holy Week, following Holy Thursday and preceding Palm Sunday. Other churches hold an Easter Vigil on Saturday night to bring the light of Christ back into the church. During Lent crosses in the sanctuary or outside churches are draped with purple cloth, which is a symbol of royalty. Jesus is often referred to in scripture as the Prince of Peace. Churches that have stationary crosses that can't be removed drape them in black, a symbol of death, on Good Friday.

One tradition on Good Friday is to make and eat hot cross buns. The bread, which is slightly sweet, has a cross on the top that represents the crucifixion. It is thought to be an English tradition that dates back 500 years.

Easter is the highest and holiest of holidays in the Christian faith. It is celebrated on the first Sunday following the first full moon after the spring equinox, usually occurring between March 22 and April 25. For many Christian congregations, the first Easter service for the year is the Service of Light. The worship typically starts in darkness on the preceding Saturday night or early Sunday morning. Light is brought into the church with candles to signify hope based on the resurrection. The service culminates with the lighting of a paschal candle, signifying Christ. Easter also signifies the end of Lent, the 40-day period of fasting, preparation, and penitence observed by the faithful.

Since the Bible does not recount what occurred on Easter Monday, most Western nations that observe the holiday celebrate it with a day off after Easter. For some, Eastern Monday is a remembrance of Christ’s death and resurrection while others use it for Easter egg hunts and polka festivals.

Easter Monday is always held the day after Easter Sunday, which is the first Sunday after the Paschal full moon. Easter Monday thus always falls between March 23 and April 26.

Legend has it that the Easter Bunny lays, decorates and hides eggs as they are also a symbol of new life.

• Easter is meant to be a symbol of hope, renewal, and new life. – Janine di Giovanni, Author and editor at Newsweek.

Ramadan (Arabic: رمضان‎ ) is the holiest month in the Islamic calendar. During the month of Ramadan, Muslims abstain from eating and drinking from sunrise to sunset. It is said God decreed this entire month holy for Muslims so that they can increase their remembrance of life after death. Muslims also abstain from all bad deeds and habits. Muslims reflect upon themselves, their religion, and the characteristics of God.

Fasting is one of the five pillars of Islam and as such it is obligatory for Muslims. Fasting and abstaining from bad habits teaches Muslims self control, humility, and generosity. Ramadan is a time for charity, family, and good deeds. Muslims fast because they believe it is vital for spiritual health. Unlike the fast of Ashurah, the fasts of Ramadan are declared mandatory by God because like salah (praying towards Mecca), fasting helps Muslims maintain spiritual and physical health.

The month of Ramadan begins when the new moon of Ramadan is sighted and ends when the new moon of Sha'ban is sighted. Muslims also believe that devils are chained up during Ramadan.

• The fast is usually broken in a family setting, where traditional foods are served. Most Muslims begin their meal with a few dates and a glass of milk because the Prophet Muhammad used to do the same. The high sugar content of the dates sends energy to weary fasting Muslim, while the fiber in the dates and the protein in the milk fills them up and prevents nausea.

O who believe, fasting is decreed for you as it was decreed for those before you; perchance you will guard yourselves (Quran, 2:183)

Yom HaZikaron (Israeli Memorial Day), the national day of public mourning, memorializes those who gave their lives in defense of the State of Israel. The Israeli Knesset established the day before Yom HaAtzmaut (Israeli Independence Day) as a day to remember and honor soldiers who lost their lives fighting in the War of Independence and in other subsequent battles. It is a solemn day during which all places of entertainment are closed and two-minute sirens are sounded throughout all of Israel, one in the evening to mark the beginning of the holiday and one in the morning, prior to the nation’s public memorial ceremony.

Israel’s national Memorial Day, when we pause to remember and mourn the thousands of Israelis who have been killed in terror attacks or who gave their lives in service to their country. May their memories be for a blessing.

Israel's Independence Day. Israel declared independence on May 14th, 1948. This was only a few hours before the British Mandate of Palestine was to draw to an end.

Yom Haazmaut is a public holiday in Israel. All commercial establishments are closed, apart from Restaurants, Cafes and Bars. Israelis celebrate Yom Haazmaut with an opening ceremony, comprising lighting of the Masuot (twelve torches, one for each of the twelve tribes of Israel). The honor of lighting each torch is given to outstanding Israelis, such as brave soldiers and policemen, scientists, artists, senior citizens and the like.

Yom Haazmaut always occurs the day after Yom Hazikaron (Memorial Day to honor fallen soldiers and soldier victims of terrorists). There are typically firework displays at night, airplane displays and bands during the day. Israeli citizens spend Yom Haazmaut with family and friends, often in a Park, on a beach or at home. The Israel Prize is given in scientific fields to notable scientists, artists and people who made a lifetime contribution to the State of Israel.

• The return of Jews to the Holy Land was also mentioned by Isaiah: On that day (the day of the redemption) a great shofar will be sounded, and those who are lost in the land of Ashur (Assyria) and those who are dispersed in the Land of Egypt will return to the Holy Land. (Isaiah 27:13).
