What is a lunar calendar 2015? The lunar calendar 2015 is a calendar that is based on cycles of the moon phases. Lunar calendars have been used since ancient times. Evidence of lunar calendars dates back as far as 32,000 years ago. Some artifacts from the Ice Age include sticks, reindeer bones and mammoth tusks with marks that academic scholars believe depict the days between moon phases.
The most common purely lunar calendar is the Islamic calendar. A feature of the Islamic lunar calendar is that a year is always 12 months, so the months are not linked with the seasons and drift each solar year by 11 to 12 days. The lunar calendar comes back to the position it had in relation to the solar year approximately every 33 Islamic years.
Lunar calendars differ as to which day is the first day of the month. For some lunar calendars, such as the Chinese calendar, the first day of a month is the day when an astronomical new moon occurs in a particular time zone. For others, such as some Hindu calendars, each month begins on the day after the full moon or the new moon. Others were based in the past on the first sighting of a lunar crescent, such as the Hebrew calendar.
The average length of the synodic month is 29.530589 days. This requires the length of a month to be alternately 29 and 30 days (termed respectively hollow and full). The tabular Islamic calendar’s 360-month cycle is equivalent to 24×15 months minus a correction of one day.
The lunar calendar for 2015 is expressed in Coordinated Universal Time (UT), the international basis for other time zones. Astronomers call one lunar cycle a lunation. For lunar calendar 2015 times in your city, please use the Time Zone Converter.
