What is the best time to transfer ETH?

Good day, I am new to the world of cryptocurrencies and am particularly interested in Ethereum. I have some ETH that I would like to transfer, but I am unsure of the best time to do so. Could you please advise me on this matter? I have heard that the timing of transactions can significantly affect the cost and speed of the transfer. Is there a specific time of day or week when the network is less congested, and therefore, the transaction fees are lower? Or is it better to transfer during peak hours, despite the higher fees, to ensure faster confirmation? I would appreciate your insights and advice on this matter. Thank you for your time and assistance.
