Some companies will have a fixed holiday calendar prevailing in their particular geography. They will set their holiday calendar, regardless of whether the day falls on a weekly off. In our company, we select 10 statutory holidays that only fall on weekdays and form a holiday calendar.
In our other locations such as the US, UK, and UAE, if a federal holiday falls on the weekend, the next first working/business day will be a holiday. This is in accordance with their labor regulations.
Apart from these, some companies in India will offer one day to their employees as an Optional Holiday. The HR department will designate 9 holidays, and the employee can choose any one holiday from the list based on suitability. Many companies have expanded their holiday calendar from 10 to 12.
Happy Holidays!
