WHEN WE LOOK FOR MARCH EQUINOX OF 11500 BC (-11500) THE SUN RISE IS NOT DUE EAST. I THINK IN ALL EQUINOXES THE SUN RISE SHOULD BE DUE EAST IRRESPECTIVE OF THE YEAR. PLEASE CLARIFY.

DO NOT SHOUT!

In the year -11500 (=11501BC) months did (probably) not have names, and years were (quite certainly) not counted with negative numbers.

The spring equinox (on the northern hemisphere) happens when the sun crosses the equator from south to north.
The autumn equinox (on the northern hemisphere) happens when the sun crosses the equator from north to south.

The name of the day when this happens is totally irrelevant.

Please read the Guide, Appendix F. Especially, F.8.
