There is no concept of "paid holidays" under the Factories Act, unlike in the Shops and Commercial Establishments Act. The Factories Act provides only for earned leave where, briefly speaking, one has to work for 240 days in a calendar year to be eligible to earn leave, which he/she earns at one day for every 20 days worked.
If you have something else in mind, please focus your question more sharply!
