Because the Zodiac is not a perfectly segmented 'clock', there is no fast and hard agreement as to the length of a Zodiac age or when the indicator clicks over. Generally a figure of length of an 'age' can be set at about 2100 years, give or take.
The 'Christian age' started with the coming of Jesus, marking the Age of Pisces; thus probably the adoption of the fish symbol for Christians. Loosely the Age of Aquarius is due - or has come. Find someone on LSD; they likely know. π€π
