question: What Austro-Hungarian composer helped produce "Princess Flavia" and "New Moon"?
answer: Sigmund Romberg
context: Title: Amavasya
  Passage: Amāvásyā (Sanskrit: अमावस्या ) means dark moon lunar phase in Sanskrit.  The word "Amāvásyā" is common to almost all Nepalese and Indian languages as most of them are derived from Sanskrit.  Ancient Babylonian, Greek and Indian calendars used 30 lunar phases, called tithi in India.  The dark moon tithi is when the Moon is within the 12 degrees of angular distance between the Sun and Moon before conjunction (syzygy).  The New Moon tithi (called Pratipada or Pratima) is the 12 angular degrees after syzygy.  Amāvásyā is often translated as new moon since there is no standard term for the Moon before conjunction in English.
  Title: Ecclesiastical new moon
  Passage: An ecclesiastical new moon is the first day of a lunar month (an ecclesiastical moon) in an ecclesiastical lunar calendar.  Such months have a whole number of days, 29 or 30, whereas true synodic months can vary from about 29.27 to 29.83 days in length.  Medieval authors equated the ecclesiastical new moon with a new crescent moon, but it is not a phase of the true moon.  If the ecclesiastical lunar calendar is accurate, the ecclesiastical new moon can be any day from the day of the astronomical new moon or dark moon to two days later (see table).

  Title: Chaand Raat
  Passage: Chaand Raat (Bengali: চাঁদ রাত, Urdu: ‎ , Hindi: चाँद रात; literally "Night of the moon") is a Bengali, Urdu and Hindi locution used in Bangladesh, Pakistan and India for the eve of the Muslim festival of Eid ul-Fitr; it can also mean a night with a full moon.  Chaand Raat is a time of celebration when families and friends gather in open areas at the end of the last day of Ramadan to spot the new moon, which signals the arrival of the Islamic month of Shawwal and the day of Eid.  Once the moon is sighted, people wish each other "Chaand Raat Mubarak" ("Have a blessed night of the new moon") or "Eid Mubarak" ("Blessings of the Eid day").  Women and girls decorate their hands with mehndi (henna), and people prepare desserts for the next day of Eid and do last rounds of shopping.  City streets have a festive look, and brightly decorated malls and markets remain open late into the night.  "Chaand Raat" is celebrated festively and passionately by Muslims (and occasionally non-Muslims as well) all over South Asia, and in socio-cultural significance, is comparable to Christmas Eve.
