Maybe, once upon a time, people didnt know about the name of day. they just through the same day. there wasnt differentiate between one day to other day. it just same. Day just a change of day and night.

Maybe, ancient people got bored with their day. In some website, they said Anglo-Saxon is a tribe who made a name of the day. wew, it's kinda cool, right?????, Impression Tribe has born. The names are still used today. They named the day based on their God. wewww. of course they were many name of God that meant they had many God. well!!

 Maybe, Anglo-Saxon named the day based on this
Sun Day become 'Sunnandaeg', or Sunday (Minggu). Moon Day become 'Monandaeg', or Monday (Senin). Mars Day become Tiw Day, is their God of War. That is 'Tiwesdaeg', orTuesday (Selasa). The name God Woden become Wednesday (Rabu). Jupiter Romans Day, God of Thunder, bcome thundey day God Thor, and this is become Thursday (Kamis). Then is Frigg, Wife of God Odin, and because of it, we have Friday (Jumat). Saturn Day become 'Saeterbsdaeg', Romans translation, and become Saturday (Sabtu).

Maybe, it is in english. but I'm very grateful the names of the days in Indonesia does not follow the teachings of Anglo-Saxons. the names of the days in Indonesia based on the names of the day in arabic except one day "minggu" means "dominggo" from jew's day. so maybe we can call minggu as ahad just like in Arab :)

Minggu ---------> Ahad
Senin    ---------> Itsnain
Selasa  ----------> Tsalatsa
Rabu    ----------> Arba'a
Kamis  ----------> Khomisah
Jumat ----------> Jumu'ah
Sabtu ----------> Sabt

and maybe, some text that i write above is true. :D
