The purpose of a calender is to measure and predict the march of time. Ancient calenders used the moon and sun to determine time and seasons.
Modern calenders are designed to determine when people will work and when they will rest. The purpose is entirely different in our time.
Current calender’s historical roots only start from Ptolemaic and early Roman periods when the Romans created a planetary week. But it didn’t gain popularity especially in Western Europe. So they adopted the 6 day Jewish week and one day of the Lord’s day of rest.
Only where there was Roman rule and expansion, the new calender and planetary week was installed. Because the Romans needed to keep track of time to monitor work of their conquered territories.
Everywhere else, it was still the lunar calender/sun rise+set for time keeping and solar calender tracking the sun for seasons.
I hear you. I am just saying ‘modern’ is ‘western’ and the west is using time to clock in and clock out people who work. That’s for why if you are rich and don’t have to work, every day is weekend and every hour can be the proverbial ‘happy hour’.
In our time, calenders and clocks are used to track our obligations and when to file tax returns. I still follow the Indian Vedic lunisolar calender for moon cycles and seasons because it keeps me grounded and sane. I feel connected to the earth and sky.
It takes some effort to compartmentalise time for different purposes, but it gives me comfort and escape from the modern world. I am not disagreeing or trying to discredit the western and modern calender. I am just sharing what works for me and the origins of it from my culture/religion.
ETA: calendar has been misspelt as calender throughout. I think I did it once and for some reason, auto complete keeps using it. I don’t want to search and correct every spelling mistake. So this is a blanket correction.
