The estimates are based on inputs from trade bodies in 30 cities in different states and stakeholders in goods and services.
"During this period (November 23-December 15), it is estimated that around 38 lakh weddings will be solemnised with a total expenditure of around Rs 4.7 lakh crore," CAIT Secretary General Praveen Khandelwal told PTI on the sidelines of a press conference.
"Last year, there were almost 32 lakh weddings with a total expenditure of Rs 3.75 lakh crore. So, this year there is (expected to be) an increase (in expenditure) of almost Rs 1 lakh crore which is a good sign for the Indian economy and retail trade," he said.
The wedding dates during the season are November 23, 24, 27, 28, 29, and December 3, 4, 7, 8, 9 and 15, CAIT said.
Khandelwal said in Delhi alone over 4 lakh weddings are expected this season, which could generate a business of about Rs 1.25 lakh crore.
