To detect the type of the energy available to your relationship, you can use the day your relationship started (or the day you were married, if you are married) and apply that date as the birth date of your partnership.

Use the birth date of your partnership to get the relationship's life path number. The online life path tool can be used for that and to get a reading. The reading is worded for an individual, but the concepts can be mentally applied to a relationship.

The pinnacle cycles, the life period cycles, and the challenge cycles can be applied similarly. The How Major Personal Numerology Cycles Affect Your Life page describes each of those cycles and what areas of your life they're likely to affect, with links to even more information.

The online numerology calculators and tools index page links to calculators for those cycles.
