"Tell him."
Vasant Rao again translated, his voice hesitant. Raj Singh examined Hawksworth skeptically. Then he turned and spoke to one of the tall Rajputs standing nearby, who walked to the end of the porch and summoned several Brahmin priests. After a conference marked by much angry shouting and gesturing, one of the Brahmins turned and left. Moments later he reappeared carrying a book.
"They have consulted the Panjika again." Vasant Rao pointed toward the book as one of the Brahmins directed a stream of language at Raj Singh. "He says there is no mistaking the date of the eclipse, and the time. It is in the lunar month of Asvina, which is your September-October. Here in the Deccan the month begins and ends with the full moon. The tithi or lunar day of the eclipse begins tomorrow."
As Hawksworth listened, he felt his heart begin to race.
The calculations at the observatory had a lot to say about your Panjika's lunar calendar. And they showed how unwieldy it is compared to the solar calendar the Arabs and Europeans use. A cycle of the moon doesn't divide evenly into the days in a year. So your astrologers have to keep adding and subtracting days and months to keep years the same length. It's almost impossible to relate a lunar calendar accurately to a solar year. Jamshid Beg, the astronomer from Samarkand, loved to check out the predictions in the Hindu Panjika.
If I deciphered his calculations right, this is one eclipse the Panjika called wrong. The astrologer must have miscopied his calculations. Or maybe he just bungled one of the main rules of lunar bookkeeping. Solar days begin at sunrise, but lunar days are different. The moon can rise at any time of day. According to the system, the lunar day current at sunrise is supposed to be the day that's counted. But if the moon rises just after sunrise, and sets before sunrise the next day, then that whole lunar "day" has to be dropped from the count.
Today was one of those days. It should have been dropped from the lunar calendar, but it wasn't. So the prediction in the Panjika is a day off.
According to Jamshid Beg's calculations, at least. God help me if he was wrong.
"Tell him his Panjika is false. If I'm to be killed the day of the eclipse, he must kill me now, today."
Raj Singh listened with increasing disquiet as Vasant Rao translated. He glanced nervously at the Brahmins and then replied in a low voice.
