In an inclusive environment, it’s crucial to keep in mind the unique needs of the Jewish campus community and to demonstrate that they are “seen” by the institution. This not only includes appropriate academic accommodations related to Jewish holidays but also culturally sensitive messaging by the institution to the campus community.
The Hebrew calendar is both solar and lunar, comprising twelve months. The lunar calendar is approximately eleven days shorter than twelve months, thus, every few years a leap month is added.
The day begins at sunset, the week begins on Saturday night, the month begins with the new moon, and the New Year, Rosh Hashanah, is in autumn.
There are twelve months in the Jewish calendar. The numbering of years is calculated from the biblical account of creation, which is traditionally understood to coincide with 3760 BCE.
The Hebrew calendar serves the religious and cultural purpose of keeping track of Holy Days, marriages, and the anniversaries of deaths. As a result of the discrepancy in days between the Jewish calendar year and the Gregorian calendar year, the date of each Holy Day will shift each year. However, the difference from year to year is usually minor and each Holy Day will occur during the same season every year (e.g. Rosh Hashanah in the fall, Pesach in the spring, etc.)
In the Bible, in addition to the Sabbath, the Holy Days are the three pilgrimage harvest festivals of Sukkot, Passover, and Shavuot; as well as the “Days of Awe,” the New Year and the Day of Atonement.
On all these Holy Days, including the Sabbath (Saturdays), work is forbidden. Many Jews who are not religiously observant will still connect with these days in a meaningful way through alternative practices.
There are other post-biblical festivals on which work is permitted, such as Chanukah and Purim. In all cases, Holy Days are marked by special synagogue services and celebrations in the home.
The Jewish Sabbath begins at sundown on Friday evening and ends after sundown on Saturday evening.
Candles are lit, the kiddush, an ancient prayer over wine, is recited, and challah (traditional bread) is served. Observant Jews go to synagogue Friday evening, Saturday morning, and Saturday evening.
All work is prohibited on Shabbat to commemorate G-d’s day of rest on the seventh day of creation as well as the Exodus from Egypt. It is a time for spiritual renewal, contemplation, learning, and family gathering.
Please note that, on Shabbat, observant Jews do not work from Friday sundown to Saturday after sundown and that, as the days grow shorter in the winter months, early departure from school or work may be required.
In Jewish tradition, work includes a range of creative activities rather than simply physical or occupational labour. On Shabbat, observant Jews abstain from using technology, driving, writing, cooking, commercial activities, and other tasks.

Kristallnacht
Night of Broken Glass
Kristallnacht marks the night on which the Jewish community of Nazi Germany, including Austria and Sudetenland, was attacked by the Nazis and their sympathizers. Synagogues and Jewish-owned properties were devastated, and Jewish people were attacked. A community-wide observance is held annually to commemorate Kristallnacht, which took place on November, 9-10, 1938.
Chanukah
Festival of Lights
25 Kislev-2 Tevet (Nov. / Dec)
A festival commemorating the victory of the Maccabees over the Hellenist-Syrians, Chanukah begins in either November or December and lasts for eight days. Chanukah has several spellings (Hanukah, Hanukkah, Chanukkah) because there is no exact English transliteration for the Hebrew word. In 164 BCE, the Maccabees, a band of Hebrews, recaptured their temple from the Hellenist-Syrians. The Temple was cleansed and purified, and the menorah (candelabrum) was lit once again as a re-dedication to G-d. When the jar of sanctified oil for the menorah was found, there was only enough to burn for one day. Miraculously, the oil burned for eight days until more was found. To commemorate this miracle, a chanukiah, a special menorah for the Holy Day, is lit for eight days; foods fried in oil, such as potato latkes or pancakes, are eaten; and children play with spinning tops called dreidels.
Tu B’shevat
Festival of the Trees
15 Shevat
A festival marking the beginning of spring in Israel, and a celebration of trees and the earth begins when the sap from the fruit trees of Israel begins to rise. It is celebrated by eating fruits and nuts that come from Israel, by planting trees, and by having picnics.
Purim
Feast of Lots
14 Adar II (Feb. / Mar)
Purim commemorates the deliverance of the Jews from a planned massacre at a time when Jewish communities were living under Persian rule in 450 BCE. The story is found in the biblical Book of Esther and is retold during this holiday. In addition to consuming traditional foods such as the hamantaschen, triangular cookies representing the malevolent enemy Haman, Purim is celebrated with costumes and loud noisemakers.
Pesach
Passover
14-22 Nisan (Mar / Apr)
Commonly referred to as Passover, Pesach is a celebration of the biblical Exodus of the Israelites, under the leadership of Moses acting in the name of G-d, from the slavery imposed by the Egyptians.
During Passover, Jews refrain from eating leavened products including bread, cakes, pizza, cereal, and others. The ritual meal, or Seder, is the most important part in the celebration of Pesach.
The Hebrew term Seder means the order in which the events of the Pesach ceremony are carried out.
During the Seder, the symbolism of each traditional food is explained, the events of the Exodus are told, and the Haggadah (a book that recounts the Exodus) is read. Pesach begins on the fifteenth day of the month of Nisan and continues for eight days.
The Seder meal is observed by most Jews worldwide.
Work is not permitted on the first two and last two days of Pesach.
Yom HaShoah

Lag B’Omer
The 33rd Day of the Counting of the Omer
17 Iyar (Apr. / May)
This day serves as a break in the mourning days between Pesach and Shavuot and is held as remembrance of the misfortunes that afflicted the Jewish people during the days of Roman domination as well as during the Crusades of the Middle Ages.
Lag B’Omer serves as a reminder of the faith and courage of Torah scholars during the harsh rule of the Roman conquerors. No special liturgy or synagogue ritual exists for this day, and most people treat it as an ordinary workday.
Yom Yerushalayim
Jerusalem Day
28 Iyar (May / Jun.)
The newest holiday in the Jewish calendar is celebrated each year on the 28th day of the month of Iyar. Yom Yerushalayim marks the anniversary of the reunification of Jerusalem under Israeli sovereignty in 1967.
Shavuot
Festival of Weeks
6-7 Sivan (May / Jun)
Shavuot recalls G-d’s gifts of the Torah and the giving of the Ten Commandments to Moses on Mount Sinai. The Holy Day commemorates the end of the spring harvest when, in biblical times, Jews brought the first fruits to the Temple in Jerusalem.
Shavuot begins on the fiftieth day after Pesach, the sixth day of the Hebrew month of Sivan (in May or June), and lasts for two days. Consuming dairy foods and using floral decorations are customary ways of celebrating the holiday. Work is not permitted during this two-day festival.
The days between Pesach and Shavuot are seen as days of mourning and are held as a remembrance of the misfortunes that afflicted the Jewish people during the days of Roman domination, as well as during the Crusades of the Middle Ages.
Tisha B’av
Destruction of the Temple
9 Av (Jul. / Aug)
In mid-summer, Jews observe the anniversary of the destruction of the ancient Temple that stood in Jerusalem. Today, Jews still turn toward the direction of Jerusalem when in prayer. Traditional Jews mark the day with a fast of twenty-five hours, from sunset to the following day’s nightfall, with prayers of mourning and with some limitations on usual workday activities.
