Do both operas Jenůfa and Oberon have the same number of acts?
Jenůfa: Jenůfa    (Její pastorkyňa, "Her Stepdaughter" in Czech) is an opera in three acts by Leoš Janáček to a Czech libretto by the composer, based on the play "Její pastorkyňa" by Gabriela Preissová. Oberon (Weber): Oberon, or The Elf King's Oath is a 3-act romantic opera in English with spoken dialogue and music by Carl Maria von Weber.
