One of the most frequently asked questions by Korean expatriates who have been posted to India for the first time is“Isn’t India a Hindu country?”no see. Of course you're half right. About 80% of the population is Hindu, so the rhythm of society as a whole follows the Hindu calendar. But at the same time India3rd most Muslim country in the worldIt is the birthplace of Sikhism and also the land where two religions, Buddhism and Jainism, were born. If you start living in India without knowing religion, you will often be confused, not understanding why the company is closed on some days, why beef cannot be served at a partner company dinner, or why the lights are on at the company even though it is December.

This article is based on the experiences of Korean expatriates who have actually lived in Delhi, Gurgaon, Noida, etc. and Indian government statistics.Population ratio and regional distribution of India's five major religions → Summary of the worldview of each religion → Major holidays to be aware of → Manners for visiting temples, mosques, and gurdwarasArranged in order.

If you need accurate, up-to-date statistics, Statistics India (censusindia.gov.in) We recommend that you check the notice.

Useful tips

Holiday schedule varies every year — based on the official holiday schedule

Most Indian holidays, such as Diwali, Holi, Eid, and Gurpurab, follow the lunar-solar calendar and the Islamic calendar, so their dates change every year. Schedule orders, meetings, and business trips based on the year's public holiday schedule announced by the company's HR and the official calendar on india.gov.in.

The correct answer for the company dinner menu is ‘a place with vegetarian options’.

When the dietary taboos of Hinduism (avoiding beef), Islam (banning pork and alcohol), and Jainism (avoiding even root vegetables) overlap, the options are greatly reduced. It is safer to choose a restaurant with a variety of vegetarian menus as a base and check the religion and allergies of partners and employees in advance.

Bring a handkerchief with you when visiting the gurdwara.

To enter a Sikh gurdwara, both men and women must cover their heads. Most offer a free bandanna (rangi), but you can save time in line by putting a large handkerchief or scarf in your bag in advance.

Please leave leather goods at Jaina temples.

Jain temples often prohibit bringing in leather belts, wallets, handbags, and even leather watch straps. Before visiting Jain temples near Ranakpur, Palitana, or Gurgaon, please organize your belongings or use the storage room at the temple entrance.

Greet with ‘Namaste’ and hold objects with your right hand.

Namaste, with both hands placed in front of the chest, is a basic greeting used regardless of religion or class. Remember to exchange business cards, gifts, and food with your right hand or both hands, and using only your left hand is considered rude.

Common pitfalls and how to solve them

!
Urgent ordering and administrative work begins just before Diwali, and delivery and replies continue to be delayed.
For a week before and after Diwali, virtually the entire country goes into holiday mode. Complete orders, contracts, and public agency applications at least two weeks in advance, and secure a replacement person in charge and emergency contact information in advance during the holidays.
!
When entertaining a partner, ordering beef and pork together creates an awkward atmosphere.
Beef is taboo for Hindu partners, and pork and alcohol are taboo for Muslim partners. Focus on vegetarian, chicken, lamb, and fish as the default menu, and be sure to check dietary restrictions before inviting, and refer to the tips in the <a href="/blog/indian-food">Indian Food Guide</a>.
!
On the day of visiting a mosque or Jain temple, entry is refused if the attire does not match the regulations.
The basics are long sleeves and long pants (or long skirts) that completely cover the shoulders and knees, and women always carry a scarf. Jaina temples even prohibit bringing in leather products, so belts, wallets, and watch straps must be inspected in advance.
!
People who participate in the Holi festival without any preparation leave strong pigments on their clothes, skin, and hair.
It is much easier to remove pigment if you wear disposable clothes and apply coconut oil or moisturizer to your skin in advance. It is safe to prepare sunglasses and a mask to prevent color powder from entering your eyes, ears, and mouth, and to avoid low-priced colorants whose ingredients are not confirmed.
!
People are stopped from taking pictures at gurdwaras and Hindu temples.
In many cases, photography is prohibited in sacred areas such as the main shrine (Garbhagriha) and in front of the temple (Guru Granth Sahib). When in doubt, ask the ushers or volunteers first if they can take pictures, and when worship is in progress, put the camera in to avoid rudeness.
