Yom Hazikaron (Hebrew: יום הזיכרון לחללי מערכות ישראל ולנפגעי פעולות האיבה‎, lit. Israeli Fallen Soldiers and Victims of Terrorism Remembrance Day) is Israel's official Memorial Day. In 2011, Israel honored the memory of soldiers killed in the line of duty and the civilian casualties too.

Yom Hazikaron is the day on which Israel honors its fallen servicemen and women. National memorial services are held in the presence of Israel's top leadership and military personnel. The day opens with a siren the preceding evening at 20:00 (8:00 pm), given that in the Hebrew calendar system, the day begins at sunset. The siren is heard all over the country and lasts for one minute, during which Israelis stop everything (including driving, which stops highways) and stand in silence, commemorating the fallen and showing respect. Many religious Jews say prayers for the souls of the fallen soldiers at this time. The official ceremony to mark the opening of the day takes place at the Western Wall, and the flag of Israel is lowered to half staff.

Gudhi Padwa (Marathi: गुढी पाडवा, often mis-pronounced as guDi padwa because ढी sounds like डी when spoken), is the Marathi name for Chaitra Shukla Pratipada.^[1] It is celebrated on the first day of the Chaitra month to mark the beginning of the New year according to the lunisolar Hindu calendar. This day is also the first day of Chaitra Navratri and Ghatasthapana also known as Kalash Sthapana is done on this day.^[2]

The word पाडवा(pāḍavā) or पाडवो(pāḍavo) comes from the Prakrit word पड्ड्वा/पाड्ड्वो(pāḍḍavā/pāḍḍavo) whose Sanskrit equivalent is प्रथमा (prathamā), which stands for the first day of the bright phase of the moon called प्रतिपदा (pratipadā) in Sanskrit.

Yugādi, Ugādi, or Samvatsarādi (Kannada: ಯುಗಾದಿ, yugādi, IPA: [juga:di] ^?, Konkani/Marathi: युगादी yugādi, Telugu: ఉగాది, ugādi ^? or సంవత్సరాది samvatsarādi) is the New Year's Day for the people of the Deccan region of India. The name Yugadi or Ugadi is derived from the Sanskrit words yuga (age) and ādi (beginning): "the beginning of a new age". ^[1] It falls on the different day every year because the Hindu calendar is a lunisolar calendar. The Saka calendar begins with the month of Chaitra (March–April) and Ugadi marks the first day of the new year. Chaitra is the first month in Panchanga which is the Indian calendar.

Ramadan (Arabic: رمضان‎ Ramaḍān, IPA: [rɑmɑˈdˤɑːn]; ^variationsPersian: Ramazan‎) is the ninth month of the Islamic calendar, which lasts 29 or 30 days. It is the Islamic month of fasting, in which participating Muslims refrain from eating, drinking, smoking and sex during daylight hours and is intended to teach Muslims about patience, spirituality, humility and submissiveness to God. Muslims fast for the sake of God (Arabic: الله‎, trans: Allah) and to offer more prayer than usual. Compared to the solar calendar, the dates of Ramadan vary, moving backwards by about eleven days each year depending on the moon; thus, a person will have fasted every day of the Gregorian calendar year in 34 years' time. Muslims believe Ramadan to be an auspicious month for the revelations of God to humankind, being the month in which the first verses of the Qur'an were revealed to the Islamic prophet, Muhammad.

The word Ramadan is derived from an Arabic root R-M-Ḍ, as in words like "ramiḍa" or "ar-ramaḍ" denoting intense heat, scorched ground and shortness of rations. Ramadan, as a name for the month, is of Islamic origin. Prior to Islam and the exclusion of intercalary days from the Islamic calendar, the name of the month was Natiq and the month fell in the warm season.^[2] The word was thus chosen as it well represented the original climate of the month and the physiological conditions precipitated from fasting. In the Qur'an, God proclaims that "fasting has been written down (as obligatory) upon you, as it was upon those before you". According to a hadith, this might refer to the Jewish practice of fasting on Yom Kippur.^[3][4]

Great Lent, or the Great Fast, is the most important fasting season in the church year in Eastern Christianity, which prepares Christians for the greatest feast of the church year, Pascha (Easter). In many ways Great Lent is similar to Lent in Western Christianity. There are some differences in the timing of Lent (besides calculating the date of Easter) and how it is practiced, both liturgically in the public worship of the church and individually.

One difference between Eastern Christianity and Western Christianity is the calculation of the date of Easter (see Computus). Most years, the Eastern Pascha falls after the Western Easter, and it may be as much as five weeks later; occasionally, the two dates coincide. Like Western Lent, Great Lent itself lasts for forty days, but unlike the West, Sundays are included in the count. Great Lent officially begins on Clean Monday, seven weeks before Pascha (Ash Wednesday is not observed in Eastern Christianity) and runs for 40 contiguous days, concluding with the Presanctified Liturgy on Friday of the Sixth Week. The next day is called Lazarus Saturday, the day before Palm Sunday. However, fasting continues throughout the following week, known as Passion Week or Holy Week, and does not end until after the Paschal Vigil early in the morning of Pascha (Easter Sunday).
