There is almost unanimous agreement that the First Point of Tropical Aries is the Transiting indicator for the Earth's Ages. Now, envision the circle of the Zodiac as a "clock-face", which most Astrologers divide into 12 equal Sign-partitions. Next, determine how to use the stars, or a star, of the Zodiacal constellations, to precisely locate WHERE the "Sidereal" (which includes Vedic) Sign-boundaries are. The "confusion" about the timing of the Ages isn't really about WHEN, it's about WHERE. Once you've chosen the Sidereal Sign-boundary positions that work best for you in interpreting Astrological -charts, you can then determine WHERE the exact position of the Transiting Age-indicator (the First Point of Tropical Aries for nearly everyone, with a few exceptions) is located in the Chart itself. And you'll know for yourself what degree of which Age we're in NOW, and you'll be able to construct a time-line for the past and the future Ages. Don't expect agreement on that, because YOUR version of exactly where the Sidereal Sign-boundaries are located will NOT be unanimously agreed upon, and a difference of only 1 DEGREE between your version and someone else's Sign-boundary locations will change the timing for the Ages by nearly 72 YEARS!
In summary, it's not confusion about the Ages themselves, but disagreement about exactly WHERE the Sidereal-signs are, that prevents unanimous agreement on the TIMING regarding the Aquarian Age.
Sidereal sign boundaries can't be true if tropical sign boundaries are true.
