Frequently asked questions

Which are the best days to sow in December 1939?

The favourable sowing and planting days in December 1939 are 3, 4, 11, 14, 15, 16, 17, 18, 19, 20, 21, 24, 25, 30 and 31 — the days on which the Moon's direction of travel and its zodiac sign agree under the traditional rule.

When should root crops be sown in December 1939?

Root crops (potatoes, carrots, onions, garlic) are traditionally sown under a waning Moon in an earth sign — in December 1939 that falls on 3, 4, 30 and 31.

Which are the rest days in December 1939?

Tradition treats the day of the new moon and the day of the full moon as days without sowing — in December 1939 those are 10 and 26 (New Moon — 10 December · Full Moon — 26 December). They suit weeding, soil work and composting instead.

How does a lunar planting calendar work?

Two rules combine. Under a waxing Moon (new → full) you sow the crops harvested above ground — fruiting, leafy and flowering plants. Under a waning Moon (full → new) you sow root crops. At the same time the zodiac sign holding the Moon decides which part of the plant is favoured: fire → fruit, earth → root, air → flower, water → leaf.

Is there scientific evidence for lunar planting?

No. The moon phase and its zodiac sign are astronomically computed and verifiable, but their link to plant growth is traditional practice, not agronomic advice. This page reproduces the rules exactly as the centuries-old farming almanacs apply them.

The moon phase and its zodiac sign are computed astronomically (tropical zodiac). The sowing rules are traditional practice taken from folk farming almanacs — they are not agronomic advice and have no scientific confirmation.
