Enter one person’s birth and the whole plate rebuilds around them: lagna, grahas, nakshatras, bhavas, all sixteen vargas, the Vimshottari tree, the chakras — then set running against the present second. Everyone you enter is kept on this device only. The only thing that ever leaves this page is the letters you type into a place field, which are sent to a public gazetteer to look up its coordinates and timezone — no name, no date, no time. (If you switch on Time table alarms for a closed browser, the times to ring are sent too, and nothing else.)
Leave this blank and everything is read at the birthplace. Fill it and the chart stays where you were born while sunrise, the muhurta, the swara cycle and the Kaarya windows move to where you actually are.
Fill in a person above and press Start this person’s clock. If you just want to see what the instrument does, — that is the printed kundali this build was validated against, not a default subject.
