Answer in Details
In the teachings and philosophy surrounding Lord Shiva, true surrender (śaraṇāgati) and detachment from the world (vairāgya) are not bound by a specific time or date; rather, they occur through sincere devotion (bhakti), self-inquiry, and spiritual practice (sadhana).
Scriptures like the Shiva Purana and teachings of Shaiva saints explain that forgetting the distractions of the world and surrendering to Lord Shiva is a gradual process that deepens with consistent remembrance of Shiva (smarana), chanting His names (japa), meditation (dhyana), and righteous living.
As Lord Shiva himself is known as the "Ashutosh"—easily pleased—He accepts sincere intentions and honest efforts from His devotees. The more you cultivate love, surrender, and detachment through daily practice and mindfulness of Shiva, the closer you come to forgetting the world and merging your consciousness with Him.
As stated in the Shiva Purana:
"With a pure heart, one who surrenders all actions and desires to Shiva attains His grace and is freed from worldly attachments."
So, your surrender will happen as you deepen your devotion and practice. Trust in Lord Shiva, persist in your spiritual discipline, and let go of expectations—the grace of Shiva will guide you to complete surrender at the right time.
