It is the identity that drives human race on this earth as well as individual and collective pragmatism, cultural authenticity, and social progress. Reason being each generation, each community and each society has tried to establish their version of understanding as the absolute truth and more righteous.
One of the means that has remained so tightly associated with the identity quest is the origination Calendar. We tend to believe to have its roots in the changing times but ostensibly speaking, it has more or less to do with the establishment of the era.
In this given time in India, two different calendars are in use; the Hindu Calendar And the Gregorian Calendar. The most visible difference between the two calendars is their basis. While the Hindu calendar is based on moon’s movement, the Gregorian one is based on the movement of the earth around the sun.
The Hindu Calendar seems to have no evidence of established by whom around the 5th century, while the Gregorian calendar was announced by Pope Gregory XIII in the 15tg century to align the celebration of the Christian festival of the Easter.
One of the most striking asymmetries is with regard to the calculation of the New Year despite the fact that both the calendars have 12 months. Vikram Samvatsaram has been officially adopted as an Indian national calendar, which celebrates the new year on the eve of the full moon of the last month. Therefore, the Amavasya is the last day of the calendar, which falls in between October 3 week and November 2nd week of the Gregorian calendar.
Based on a Solar system, the Gregorian calendar has finalized the day of the new year. According to the western calendar, December is the last month and the first day of the January begins the mark of the new year. The Gregorian reforms were introduced to finalize the date of the Easter that should be aligned with the Church’s comfort.
Another major difference is about the how the days are calculated while the Gregorian calendar bases its premise on how the Earth revolves around the sun, while the Hindu calendar has its calculations defined on how the moon revolves around the Earth.
One major change that can be seen between two is about the number of days. While the Hindu calendar has fixed 28 days cycle for each month, the Gregorian calendar either has 30 or 31 days in its months. It is, therefore, Hindu calendar adds “Adhik Maas” each year to meet the target of 365 days.
One of the bases of the calendar is the seasons. Here too, two calendars differ with each other. While According to the Hindu Calender, there are 6 official seasons, whereas in English calendar there are only 4 seasons.
Last but not the least. If you think that Hindu calendar has 60 minutes of our divided into 24 sections, you are wrong. It has each Muhurta of 48 minutes and has 15 Muhurtas to calculate the day.
However, in totality, if you see, it has to do with the identity of the community, civilization or the era. More or less, they reflect the supremacy of the power of that time, which has a larger influence on the mass. The calendar is more about the local culture, festivals, and seasons. Therefore, it’s anything but natural to have differences.
