1. Day:
The period from sunrise to the next sunrise defines one day.
The period from sunrise to the next sunrise defines one day.
A repeating seven-day cycle used for scheduling.
Divided into lunar months (based on moon phases) and solar months (an abstract concept dividing the year).
Lunar Year: 12 months marked by the moon’s cycle, totaling 354–355 days.
Solar Year: The Earth’s orbit around the sun, lasting approximately 365 or 366 days.
This journey begins with the principles of the 7th century. For those unfamiliar with the context, check out our introductory video to embark on a fascinating exploration of time and its measurement.
The Quran provides timeless insights into time measurement:.
Quran [2:259]: A man slept for 100 years and awoke, thinking it was only a day or part of a day. Equation: Over 100 years, the same weekday shifts back by one or two days
Quran [18:25]: "And they stayed in their cave for 300 years, adding nine. Equation: If Day 1 starts on a Friday, 300 years later, the same date could fall on either Saturday or Sunday."
The Quran’s descriptions align with modern science: 1. Days repeat after 7 cycles. 2. Every 4 years, a leap year adds an extra day to balance the calendar. 3. A century divisible by 400 (e.g., the year 2000) also includes a leap day. This demonstrates the Creator’s precise knowledge of time, guiding humanity long before modern calendars existed.
