These days are called Fixed, Permanent or Foundational because they are good for establishing or creating anything that you want to last or endure – that could be a house, a company, or a project; it could be to establish a garden, or build anything from a fence, to a skyscraper or to a non-profit foundation that has legacy and even marriage (in the right circumstances).
These foundational days may not have the movement and flow of the first two types of Green Days, but the steady, grounded stability that these days provide are an important piece to the development of any project, object or relationship we create.

Establishing projects or building on these days embeds longevity into the project. The responsibility of using these days asks that you have done your homework, since creating things on these days ensures that it will take more effort to undo or have lasting repercussions in the attempt to take it apart. Thus, you can see if someone was getting married for a second (or more) time, they might want to use one of these days to help them make the marriage last.

Actions taken on these days create heritage, longevity and objects, art and ideas, products or companies that can live beyond us.

Activities that are good on these kinds of days are:

• Pour the foundation of a house
• Establish a garden or make a major change to some land.
• Plant trees
• Break ground or begin building a home, commercial building or temple or church
• Marriage

New stone work, fences and other installations of large, heavy materials that are intended to stay for long periods of time. These days feel different than the other 3 kinds of Green Days because the energy is fixed, so this day’s activities are best focused on endeavors which are meant to last a long time or have duration.

This is literally about laying the foundation to the home that will last lifetimes. A house built on solid foundation will last through the test of time, weather and unforeseen challenges. This will not be the house that the big bad wolf can blow down. This house will be more like the castle that Andrew Carnegie built. The metaphor translates to making anything; think re-bar, reinforced concrete and a well-built foundation to your company, idea, artistic creation, family, non-profit or investment fund. This type of green day is used to establish things that will last and endure.
