The ISO International Standard Organizational (AKA Scientific/Astronomical) date format for today is:
year-month-day
2024 JUN 25
2024/06/25
It progresses rationally from left to right in descending order of significant digits.
It's the format used by NASA/JPL, observatories and astronomy authors including Jean Meeus.
Other date formats twist the ordering in various confusing ways.
The collective usage of ISO dates can avoid confusion when writing for the astronomy community. This is especially true when the month is written with letters. Although, with all numerals a computer program sorts ISO dates in proper order.
Yes, the ISO format is different from what I learned in grade school, and another version I was taught in the army. But over 20 years ago, I opened a section of my website for the benefit of amateur astronomers, and have gotten quite used to ISO dates.
