I do; and I have known it for a long time. It's true and real. For the Gregorian Calendar in its first development only had 10 months: March (the first month); April (the second one); May (the third one); June (the fourth one); July (the fifth one); August (the sixth one); September (the seventh one); October (the eighth one); November (the ninth one); December (the tenth one). And it is really easy for us, the Indonesians, to catch the meaning of the order of these months from their names, for we also use many terms of sanskrit words in our language. Just see, the word of September goes with "Sapta" means seven or the seventh; the word October goes with "Okta or octave" means eight or the eighth; the word November goes with "Nofa or Nova" means nine or the nineth; and the word December goes with "Dasa" mean ten or the tenth. Many of us get ridiculous to see the order of the Gregorian Calendar at this time. Since January and February joined the other tens more than one thousands year after its first launching in 1 A.D. They should have been placed in the eleventh and the twelfth month, not in the first and the second one as we all see at this time.
