The day has been chosen because of unique astrological aspects that cross their personal natal charts indicating great beginings and future joys.
Friday's lunation also includes a moon/jupiter conjunction in Aishwarya's fourth house of kith and kin and falls close to her husband's Sagittarius/Capricorn ascendant.
The happy couple have just returned home from the Cannes Film Festival where Aishwarya was unable to do much PR work publicising her new movie after doctors told her to take it easy.
And the first thing she and husband Abhishek did on their return home was to pay a visit to Mumbai's famous Siddhivinayak temple early this morning to take part in Aarti, in an act of joy and thanksgiving ahead of a planned announcement at the start of the weekend.
Sources close to the former Miss World and famous Bollywood actress today said Aishwarya would wait for the results of a scan later tomorrow before releasing a statement.
The couple are said to be 'over the moon' and looking forward to the next generation of their awesome movie lineage.
