The best time to play poker is when you are mentally fresh and fully focused, because decision quality drops quickly when you are tired or distracted. From a profitability point of view, evenings, weekends, and holidays are often better since more recreational players are active and games tend to be softer. The ideal situation is combining both factors playing when your concentration is high and the player pool is weaker. Avoid sessions when you feel fatigued or emotionally off, because that’s usually when mistakes and losses increase.
