Rambu Solo' (season)
Chiefly July to September, set by the family
Not a single date. The time is set by each family according to readiness and the presence of migrants; July–September is a season, not a rule.
Most ceremonies in this corpus do not fall on a fixed Gregorian date. This calendar therefore does not force a date: it states how the timing of each is determined, and declines to display an estimate where the determination cannot be computed.
