What cultures still use a lunar calendar?
Present-day lunisolar calendars include the Chinese, Vietnamese, Hindu, and Thai calendars. Synodic months are 29 or 30 days in length, making a lunar year of 12 months about 11 to 12 days shorter than a solar year.
Why did we stop using lunar calendar?
Lunar calendars are problematic, due partly to the fact that the average lunation is not a whole number. If ’29’ were the number used to mark the lunar month, the calendar would very quickly get out of sync with the actual phases of the moon. So what happens is that these calendars must be ‘adjusted’ from time to time.
Is lunar calendar inaccurate?
Lunar calendars may have been accurate when establishing months. But, it’s a bit off when it comes to the number of days there are in a year. A lunar year is only 354 days. So, if you were to use an accurate lunar calendar, you would lose 11 days annually compared to the widely used Gregorian Calendar.
What religion uses the lunar calendar?
The Islamic calendar is based on the lunar system. That’s why Muslims have to sight the new crescent at the end of the month on the 29th day. If some Muslims see the crescent with the naked eye, then all Muslims accept their claim and the new month begins after sunset.

Does Christianity use a lunar calendar?
The civil versions of the Julian and Gregorian calendars are solar, because their dates do not indicate the Moon phase – however, both the Gregorian and Julian calendars include undated lunar calendars that allow them to calculate the Christian celebration of Easter, so both are lunisolar calendars in that respect.
Does China follow the lunar calendar?
Contrary to what you might expect, the Chinese calendar isn’t a lunar calendar. Instead it’s lunisolar—meaning that it’s based on measurements of the phases of the moon, but also on the position of the sun in the sky.
