What if there is no good muhūrta and the date can't change — surgery, exam, flight?
go ahead — life and duty come first; remember God, avoid only what you easily can, and trust the doctors and your preparation.
Muhūrta is a tool for choosing among options. When there is no real choice — a hospital schedules surgery, a board fixes an exam date, a flight leaves when it leaves — the tradition itself says not to let timing override necessity. Never delay medical treatment for a muhūrta.
There are small steps you can take with peace of mind: if there is flexibility within the day, prefer Abhijit or a good choghaḍiyā and skip Rāhu kāla; offer a prayer to Gaṇeśa, the remover of obstacles, before leaving; chant a mantra you love; and give a little dāna.
The Gītā's teaching fits well here: do your duty fully and offer the result to God. Good preparation, skilled professionals and a calm mind are themselves the most auspicious “timing” you can bring.
