It is highly recommended to book your movers at least 2 to 4 weeks in advance, especially if you’re planning a move during peak seasons. In Kolkata, the busiest periods are between October and March (post-monsoon and winter) and particularly around the Durga Puja festival when many families relocate. Booking early ensures you get your preferred date, better rates, and sufficient time for the company to conduct a thorough pre-move survey. Last-minute bookings often come with premium charges or limited availability.
