Although a clear Gregorian date is not found till date on which "Jamnagar" was established, most of the historian believed the year to be 1540 AD, some claim it to be 1543 AD, but by going through Indian calendar year 1596 Shravan (Sud) 7 is known to be foundation stone laying day or Birthday of Jamnagar (Nawanagar)
Three foundation stone were laid; one can see one of them in "Dilawar" cycle shop near Wellington Circle (Darbar Garh). Second one can be seen in Mr. P. H. Sheth home near Ram Hotel (Darbar Garh). Third foundation stone location is not known.
