The classic Jewish sources (Seder Olam, accepted and cited Bavli in several locations; for example, see the discussion on Avoda Zara 9a) state that Bayis Sheini (the Second Temple) stood for 420 years. I have a vague recollection that other (accepted!) Jewish sources give other numbers, but I cannot remember which sources or what numbers they give. Can anyone help out?
Please note I am asking for specifically (traditional) Jewish sources. I know many secular historians like the number 586; that's not what I'm looking for.
Update: Although I accepted @Joelk's answer, this question (like many that may be asked on Mi Yodea) can have more than one valid answer; specifically, other numbers cited by other sources.
