Is announcing the time of an eclipse considered knowledge of the unseen?

Question:
May Allah protect you, Your Eminence, father. The questioner asks: If someone says that an eclipse of the sun or moon will occur on such-and-such a day, is that a claim to knowledge of the unseen?

Answer:
No, this is from the science of calculation regarding the movement of the moon and the sun. The calculators have known this for a long time. Is it from the knowledge of the unseen? Because it is determined through calculation, and what is determined through calculation is not from the knowledge of the unseen.
