What language and currency does Klasku use?

Indonesian throughout the tenant panel, the Parents Portal, and the Teachers Portal, including the messages sent to parents. The currency is the rupiah, written out in full as Rp 1.250.000, so no figure has to be interpreted twice.

Every date and time is computed in the Asia/Jakarta time zone — schedules, make-up deadlines, invoice due dates, and automatic issuing. Month names are never abbreviated in messages, so a due date cannot be misread.
