It is a fact that the English names of days and months are derived from the names of Roman and Norse gods.
For example Wednesday is derived from Odin, Thursday from Thor, Friday from Freya, Saturday from Saturn, Sunday from Sun, Monday from Moon. Similarly January from Janos, March from Mars, May from Maia, June from Juno, July from Julius, August from Augustus etc.
Is it wrong or haram to use these names? What is different between this and using the names of arab idols like Hubal, Laat, Uzza and Mannat?
