For Lao Loum, Lao Theung, and Lao Sung, the rhythm of life is strongly tied to the changing seasons and the requirements of farming. For swidden farming villages, the work year begins in January or February when new fields are cleared. This time of the year is also good for hunting and for moving to a new village. Opium farmers harvest the resin between January and March, depending on location and variety of poppy, but otherwise there are few agricultural activities. Swidden fields are burned around March and must be planted in May or June, just before the first rains. From the time the seeds sprout until August, work revolves around the never-ending task of weeding. Hunting and fishing continue, and with the coming of the rains, the forest begins to yield new varieties of wild foods.

For paddy farmers, the agricultural year begins with the first rains, when a small seedbed is plowed and planted. The seedlings grow for a month or so while the remaining fields are plowed and harrowed in preparation for transplanting. Transplanting requires steady work from every able-bodied person over a period of about a month and is one of the main periods of labor exchange in lowland villages.

Swidden farmers begin the corn harvest as early as September, and short-season rice varieties mature soon after the corn. Paddy rice seldom ripens before October, however, and the harvest may continue through early December in some areas, although midNovember is more usual. Even late swidden rice is finished by early November. Harvesting and threshing the rice are the principal activities during the second period of intense work in the farm year. Dry-season rice farmers repeat the same cycle, but vegetables, tobacco, or other cash crops require a more even labor input over the season.

Food availability parallels the seasons. Wild foods and fish are abundant during the rainy season, although the months just before the corn ripens may be difficult if the previous year's harvest was inadequate. Fruit is available during the rainy and cool dry seasons, but becomes scarce, as do most vegetables, from March through May. Hmong and Mien celebrate their new year in December or January, when the harvest is complete but before the time to clear new fields. Lowland Lao celebrate their new year on April 15, also shortly before the start of the farming year. The harvest is marked by the That Luang (see Glossary) festival, on the full moon of the twelfth lunar month, which falls in late November or early December (see Buddhism , this ch.).

Because most roads are in poor condition, travel in the rainy season is generally difficult, and villagers tend to stay close to home, because of farmwork as well as the ever-present mud. The dry season brings easier land travel and the free time it allows. Since the late 1980s, a few rural villagers have begun to travel to regional population centers in search of temporary wage employment, often in construction.
