The current calendar the world uses was designed by man, which is why it's horribly inaccurate. Some months have 30 days, others have 31, and there is a leap year every 4 years to compensate for the errors! It used to be a 10 month calendar, which is why the prefix "Deci" means 10, even though December is the 12th month. Likewise, "Novi" means 9, "Octo" means 8, and "Sept" is 7.
The true calendar is designed by God, and is a 12 month lunar calendar. You don't need someone to tell you what day of the month it is, Subhan Allah! You can just look at the sky! Don't forget it's sunnah to fast during the "white days" (i.e. 13th, 14th, and 15th of the month) which are easy to spot by the full moons: "It is He who kindles the light of dawn, and has made the night for you to rest, and the sun and moon as a means of calculation. This is the design of the Majestic and All-knowing God." -[ Al-An'am (The Cattle), 6:96] "According to the Book of God, from the day He created the heavens and the earth, the number of months are twelve.." -[Al-Taubah (The Repentance) 9:36]
