The spelling is eccentric, but you may mean hajj, the Arabic word for pilgrimage, or chag (with a ch as in Loch Ness or J.S. Bach), the Hebrew word for pilgrimage. Muslims go on hajj to Mecca, and in the days before Imperial Rome destroyed the Jerusalem Temple, Jews want on chag to the Temple.

Muslims go to Hajj as it is one of the Five Pillars of Islam, which are the core beliefs and practices that all Muslims are expected to follow. Hajj is a pilgrimage to the holy city of Mecca in Saudi Arabia, where Muslims commemorate the actions of the Prophet Ibrahim and his family. It is a religious duty for Muslims who are physically and financially able to perform Hajj at least once in their lifetime. The pilgrimage serves as a way for Muslims to seek forgiveness, purify their souls, and strengthen their faith.
The most obvious similarity is that all three involve fasting, abstaining from certain types of food or from eating at certain times. During Yom Kippur, Jews fast for 25 hours; during Lent Christians will not eat milk, eggs and other foods (which are used up to make pancakes the day before Lent begins) - some Christians abstain from all animal products during this period, while others fast for a portion of it and during Ramadan Muslims maintain a strict fast - during which nothing must pass the lips, effectively banning them from drinking and smoking too - between dawn and nightfall.Another similarity - the one I suspect the question refers to if it forms a part of your school homework - is that all three festivals focus on repentance, self-cleansing and absolving oneself in the eyes of G-d. Jews spend the ten days between Rosh Hashanah and Yom Kippur putting right any sins they have committed in the previous year and taking steps to better themselves so that they will not commit those sins again, then spend Yom Kippur deep in prayer so that G-d will forgive them; Christians, through prayer, charity, penitance and self-denial, solmnly prepare themseves spirtiually for Easter when they remember the death and rebirth of Christ and Muslims use Ramadan as an opportunity to focus on enlightenment and spiritual cleansing, taking a step back from their everyday lives in order to strengthen the link between themselves and Allah.
