This year, three debating societies are celebrating their lustrums. For those unfamiliar, lustrums are five-year periods which allow a company, organization or in our case, a society to celebrate its birthdays. TU Delft Debating Club is celebrating its very first lustrum, Leiden Debating Union its third and as the oldest society of the Netherlands, Erasmus Debating Society is very excited to celebrate its sixth. Naturally, such big celebrations call for huge parties, from dinners, to galas, to lectures, to party weekends; societies are determined to celebrate in style.
