Every day carries its own energy. Learn to align your actions with cosmic rhythms.
High Energy Days
When stars align in your favor
When planetary aspects are favorable, your actions carry cosmic momentum. These are the days to:
- → Launch new projects, businesses, or creative endeavors
- → Initiate important conversations and negotiations
- → Take action on major decisions—career moves, investments, proposals
- → Schedule beauty treatments and wellness rituals for maximum effect
Low Energy Days
When the cosmos calls for patience
Challenging aspects don't mean bad days—they're invitations to slow down and focus inward:
- → Reflect on your progress and recalibrate your goals
- → Complete unfinished projects instead of starting new ones
- → Rest and recharge—meditation, journaling, self-care
- → Plan for the next high-energy window to take action
Sidera shows you exactly which type of day it is—so you always know when to push forward and when to pause.
