The Carnival of Malmedy is locally called Cwarmê. Even if Malmedy is located in the east Belgium, near the German-speaking area, the Cwarmê is a pure walloon and Latin carnival. The celebration takes place during 4 days before the Shrove Tuesday. The Cwarmê Sunday is the most important and insteresting to see. All the old traditional costumes parade in the street. The Cwarmê is a "street carnival" and is not only a parade. People who are disguised pass through the crowd and perform a part of the traditional costume they wear. The famous traditional costumes at the Cwarmê of Malmedy are the Haguète, the Longuès-Brèsses and the Long-Né.

Ancient tables provided the sun's mean longitude. Christopher Clavius, the architect of the Gregorian calendar, noted that the tables agreed neither on the time when the sun passed through the vernal equinox nor on the length of the mean tropical year. Tycho Brahe also noticed discrepancies. The Gregorian leap year rule (97 leap years in 400 years) was put forward by Petrus Pitatus of Verona in 1560. He noted that it is consistent with the tropical year of the Alfonsine tables and with the mean tropical year of Copernicus (De revolutionibus) and Reinhold (Prutenic tables). The three mean tropical years in Babylonian sexagesimals as the excess over 365 days (the way they would have been extracted from the tables of mean longitude) were 14,33,9,57 (Alphonsine), 14,33,11,12 (Copernicus) and 14,33,9,24 (Reinhold). All values are the same to two places (14:33) and this is also the mean length of the Gregorian year. Thus Pitatus' solution would have commended itself to the astronomers.

Roughly 70% of the area in the RSFSR consisted of broad plains, with mountainous tundra regions mainly concentrated in the east. The area is rich in mineral resources, including petroleum, natural gas, and iron ore.
