These calendars may be useful to those wishing to investigate possible relationships between natural phenomena or personal well-being and local changes in gravity.
It contains a table of predicted hourly (in local winter time) variations in the Earth’s gravitational acceleration over the course of a year, covering a city and the area extending for several hundred kilometers around it.
In addition, the intensities of sunlight and moonlight (their vertical components) are provided, as they also have cyclical effects on living organisms.
Small but systematic fluctuations in Earth’s gravitational acceleration occur throughout the globe. Their most visible manifestation is the rise and fall of ocean tides, and measuring these fluctuations requires the use of gravimeters, as weighing scales are unable to detect such small changes.
The data presented were calculated using a proprietary algorithm.
Calendars are currently being developed for the following countries: Argentina, Australia, Brazil, Canada, China, China – Hong Kong SAR, China – Macao SAR, China – Taiwan Province of China, France, Germany, Indonesia, Ireland, Israel, Japan, Mexico, Qatar, Republic of Korea, Russian Federation, Saudi Arabia, Singapore, Spain, Türkiye, United Arab Emirates, United Kingdom, and the United States of America.
