The calendar I use is the Luni-Solar calendar, as prescribed inthe Qur’an.
Surah Yunus, Verse 5:
هُوَ الَّذِي جَعَلَ الشَّمْسَ ضِيَاءً وَالْقَمَرَ نُورًا وَقَدَّرَهُ مَنَازِلَ لِتَعْلَمُوا عَدَدَ السِّنِينَ وَالْحِسَابَ مَا خَلَقَ اللَّهُ ذَٰلِكَ إِلَّا بِالْحَقِّ يُفَصِّلُ الْآيَاتِ لِقَوْمٍ يَعْلَمُونَ
He it is Who made the sun a shining brightness and the moon a light, and ordained for it mansions that you might know the computation of years and the reckoning. Allah did not create it but with truth; He makes the signs manifest for a people who know.
(English – Shakir)
via iQuran
Thus, I use the Luni-Solar calendar
The current hijriyah calendhar only utilize the phase of the moon
For me, I use the luni-solar calendar and keep track of the time, the days and the months.
Q: I still don’t get your point, there are +/- 12 moon cycles a year, such is the rotation of the earth around the sun. This Calendar has been used for thousands of years..?
Produce a contradiction between the current system, and ‘your system’. Conclude with telling us when ‘your’ Ramadan is then.
A: Hijriyah system only use lunar calendar. While the quran mention that we must utilize both moon and sun to count the days and months.
Root word for ramadhan is Ra-Mim-Dad, the scorching heat.
The time for the Ramadhan must always stay the same. Using lunar or solar calendar only will result in Ramadhan happening at different time each year.
This luni solar calendar has leap year, known as the metonic cycle.
The metonic cycle has been used by other people too since ancient time: the jews, the chinese and Hindu
What does Al-Qur’an say about metonic cycle:
74:29-31
Please google more on luni-solar calendar and metonic cycle.
Q: I think the point of the ayat is to use the moon and the sun together when deciding year calculation is because the moon will never show its light if the sun doesn’t shine upon the moon parts in periodic time period?
So impossible to use moon calculation without interference from the sun who gives its light, because the moon will foreverly dark and unseen without the sun..
By the light reflection of the moon from the sun which changed periodically, we can calculate the 12 months cycle mentioned in Qur’an 9:36
That’s my understanding about the ayat so far…
A:: Yes, the sun is used to mark the changing of days, while the moon is for the changing of months.
My point is, using luni solar calendar will always lead to Ramadhan falls on Summer, thus fitting the description of the “scorching heat
4:29 lawwahatun = sign
74:30 the nineteen (metonic cycle)
74:31 pay attention to the “iddatahum” (the number) the number nineteen is a sign from Allah, it is supposed to make us more believe while at the same time it serves as a trial for the disbeliever
C: Yes, this notion is logic. I had read/hear about Ramadhan story on combating “nafs” by using the scorching heat (Ra-Mim-Dad).
yes, I am trying to search it.
The Hebrew, Jain, Buddhist, Hindu and Kurdish as well as the traditional Burmese, Chinese, Japanese, Tibetan, Vietnamese, Mongolian and Korean calendars (in the east Asian cultural sphere), plus the ancient Hellenic, Coligny, and Babylonian calendars are all lunisolar. Also, some of the ancient pre-Islamic calendars in south Arabia followed a lunisolar system.[1] The Chinese, Coligny and Hebrew[2] lunisolar calendars track more or less the tropical year whereas the Buddhist and Hindu lunisolar calendars track the sidereal year. Therefore, the first three give an idea of the seasons whereas the last two give an idea of the position among the constellations of the full moon. The Tibetan calendar was influenced by both the Chinese and Buddhist calendars. The Germanic peoples also used a lunisolar calendar before their conversion to Christianity.
Balinese Hindust and also the Old Javanese “Kejawen” still using the calendar that marks the calendar for farming and harvesting based on Moon intertwined with Sun. Perhaps, this is the exact example of Luni Solar Calendar.
And on the based of those calendar, they are calculating the good day for them to conduct significant change of life meticulously with the person date of birth, and soon..soon
Q: Share his though about calendar in Islam, to decided Ramadhan month.
And I also personally questioning about the ordained calendar including names of days in Islam.
If in the secular world we are knowing Julian calendar based on Sun.
Muslim refer to Moon, and the jumuah day derived from history of war.
All this kind of things have me questioning
However, I do not have time to study it further because my priority is in the Quran ritual of wudu, salah, hajj, and hijab covering.
Here the caption from @Bachrun

74:30 the nineteen (metonic cycle)

A: The current Islamic calendar is based on the lunar cycle, but Quran identifies with both lunar and solar
There is no law that states you must be exact with time or else the stars and a sidereal day would be the best method. A calendar is just so humanity can keep track and sync the natural cycle.
For example both winter and summer is computation based on seasonal change in the Quran.
You can look at the moon any time of the night and know exactly what time of the month it is.
The same can not be said about the sun unless you know what time it is of the day (sunrise and sunset is pretty easy but the rest of the day isnt easy)
Like after you open your fast go look at the moon and you’ll know exactly how much of Ramadan you’ve completed.
You also know because of the sun the weather. So both are used.
Notice sis in the next ayat it mentions sun and moon not just moon.
[10.5] He it is Who made the sun a shining brightness and the moon a light, and ordained for it mansions that you might know the computation of years and the reckoning. Allah did not create it but with truth; He makes the signs manifest for a people who know.
Jummah sis in the Quran doesn’t specifically say Friday but it has been translated as such.
The word in the Quran for Friday is
l-Jum’ati which means to collect or gather, bring together, to contract, assemble or congregate, unite or connect or form a connection, bring into a state of union, reconcile or conciliate
So the line in the Quran is
day yawmi
(of) The Gathering l-jumuʿati (translated as Friday due to Jewish influence)
then hasten fa-is’ʿaw
to ilā
(the) remembrance dhik’ri
(of) Allah l-lahi
and leave wadharū
the business. l-bayʿa
So Quran says whenever you are called to prayer on the day you gather, remember Allah and cease trading/commerce, not specifically Friday.
