Post-Ramadan​ Item

I feel like that  although Ramadan is already over I need to post a Post-Ramadan Item, just  complete the Ramadan series for you guys for this year.

As you might already know or might not know the Islamic Calendar is based on the change of the position of our moon or called the motion of our moon .
It has also 12 months named as the following:

1. Muharram 7. Rajab
2. Safar 8. Sha’ban
3. Rabi’ al-awwal (Rabi’ I) 9. Ramadan
4. Rabi’ al-thani (Rabi’ II) 10. Shawwal
5. Jumada al-awwal (Jumada I) 11. Dhu al-Qi’dah
6. Jumada al-thani (Jumada II) 12. Dhu al-Hijjah

As you can see we now already enter the 10th month which in Shawwal. Actually, a nice note is that each month starts by seeing the new moon by a human observer eye.

The new moon may be calculated very precisely. Nevertheless, the actual visibility of the crescent is much more difficult to predict. It depends on factors such as weather, the optical properties of the atmosphere, and the location of the observer. It is therefore very difficult to give accurate information in advance about when a new month will start.
