Biodynamic Calendar App


The calendar is based on the movement of the Moon around the Earth in its cycle of 27 days and in its passage through the twelve regions of the zodiac, the sidereal rhythm. During this process this celestial body transmits cosmic forces to the Earth and to the different beings that inhabit it. In each of these days plants receive cosmic stimulations which affect their different organs (roots, leaves, flowers and fruits) and which manifest beneficial effects upon them.

In the monthly presentation the effects are represented by the corresponding symbols, as well as the time of the beginning of the influence. We can also observe the Moon phases and the periods of ascending  or descending Moon.  Unfavorable times are marked thus (---).

Opening daily the agenda we have the position of the Sun in the zodiac and the details of astronomic events.  Here we can make notes of agricultural activities for writing reports.

a) Days and hours  with effect on the root - element  Earth

That means sowing, transplanting and cultivation of vegetables whose production occurs in the soil forming comestible roots and tubercles, such as beetroot, carrot, potato, onion etc, are enhanced (this phenomenon depends on the group of constellations linked to the element earth, namely Taurus, Virgo , and Capricorn). These days bring good results and a better quality of storage for the crop. The making of combs is enhanced by working on the bee hives, dealing with the bees

b) Days and hours with effect on leaves and stems- element Water.

We recommend sowing, transplanting and cultivating plants from which the intention is to use leaves and stems, namely colewort, salads, spinach, chicory, parsley, green onions, sugarcane and pasture. It is preferable to transplant in the time of Descending Moon  (in this time the plant sap descends, and  works related to formation and transplanting young plants, since they form roots better). It is also a proper period for pruning and cutting of wood.

Leaf days are not proper for harvesting, since products harvested in these days start decomposing in a shorter time.

For harvesting leaf plants, such as cabbage, we recommend days and hours for flower and fruit. Also works related to honey can be done (centrifugation, bottling), but bee hives should not be disturbed. Leaf days are related to the group of constellations connected to the element water (Pisces , Cancer  and Scorpio.

c) Days and hours with effect on flowers – element Light

We recommend sowing, transplanting, cultivating and harvesting plants appointed to production of ornamental flowers or those used for medicinal purposes. Seeds of oil plants managed in flower hours are richer in oil, and it is more advantageous harvesting these plants in flower days. Vase flowers, if cut in these days, have a more intense scent, endure longer and the plant soon form new lateral shoots. Dried flowers harvested in flower days maintain the luminous intensity of the colors. Broccoli should be harvested in flower days. Working on the beehives enhances the collection of pollen and laying of eggs. This occurrence is related to the group of air constellations (Gemini, Libra and Aquarius ). In an Apogee day (Ag) the impulse FLOWER is stronger than the rhythm of sidereal Moon when it is situated in leaf or root,  5 hours  before and  3 hours after the moment of  Apogee.

d) Days and hours with effect on the fruit - element Warmth.

They are appropriate for sowing, transplanting and cultivating plants that produce fruits and seeds, including tomato, cucumber, pumpkin, beans and corn. Sowing oil plants in these days and hours bring the best yield in seeds, although one can achieve better oil yield sowing the oil plants in flower days.  Leo days are specially adequate for seed producing plants.

Transplanting is favored in the period of Descending Moon. Harvesting in these days allows fruits and seeds to have a better storage quality and a better regeneration force.

For grafting, besides choosing a fruit day, one should prefer the period of Ascending Moon   (in which the sap rises).  Flowers and plants cut in these conditions take longer to wither. We also recommend harvesting leaf plants in this period.

In the work with bees, handling the boxes, one can cause bees to collect nectar.  These days are related to the constellations of the fire group. (Aries , Leo  and  Sagittarius).


a) Ascending Moon 

When the Moon is located in the lowest point of its orbit, in front of the constellation of Gemini, it starts to become ascending. It describes every day a longer bow in the sky. Its points of rising move towards southeast, and its points of setting towards southwest. It should not be confounded with the phase of Waxing Moon. During Ascending Moon juice formation in plants increases. The plant is full of juices and forces in the upper parts. This period is favorable for grafting, so this effect is enhanced by working with fruit plants in this period. In case of plants with flowers one should take advantage of corresponding flower days.

The same is valid for grafting works. Fruits harvested in this period can be kept fresh and juicy longer. This epoch is also adequate for cutting Christmas pine tree, which maintain the needles longer, and the scent is more pleasant if the cutting is done on flower days. This relationship is inverted in the northern hemisphere.

b) Descending Moon

When the Moon reaches the highest point in its monthly orbit, in front of Sagittarius, it becomes descending. The bows become everyday lower, the points of rising move towards northeast, and the points of setting towards northwest. For sowing, transplanting and tree planting, ornamental plants and hedges we choosen the period of descending Moon, which should not be confounded with the phase of Waning Moon. During planting time plants form roots and are quickly connected to the new spot. We  can increase this impulse for each type of plant if, from the planting times on, we choose  the corresponding leaf days for leaf plants  and root days for tubercles,  doing the same way for fruit and flower producing plants.

Thus we obtain, besides the impulse for root formation, an enhancing on the different organs of the plant. In this period the juice content decreases, so it is recommended for pruning trees and hedges and cutting wood as well as for manuring meadows and fields and planting fruit trees.

Remark: near the Equator the effect of this rhythm is little noticeable.


We recommend to avoid sowing in the time of transition between constellations in about one hour.

These are periods caused by eclipses, Moon   nodes and planet conjunctions. These periods are not recommended for agricultural activities. If, for reasons of time, it is necessary to sow on unfavorable days, one can do the cultivation work on favorable days and thus achieve a balance.

Ascending and descending Moon Node:  point of intersection where the Moon crosses the ecliptic in its ascending and descending periods.  It brings mostly negative effects of about two hours. For planetary nodes of Mercury and Venus the unfavorable period lasts about 12 hours. 

Perigee - Pg: the point where the Moon is nearest the Earth. It is also considered unfavorable for about 12 hours. This period is inadequate for agricultural activities in general.

Apogee Ag: it is the moment in which the Moon is most distant from the Earth.

Mapeamento Biodinâmico

Pesquisa de Mercado

Este mapeamento tem o objetivo de entender como o consumidor final percebe a agricultura biodinamica, se ele a reconhece, se compreende suas vantagens etc. Trata-se de um marco zero para iniciarmos anualmente um monitoramento da evolução dos habitos de consumo em relação a agricultura biodinamica.
