In Finland, many holidays have a Christian background. Among other religious observances, Christmas and Easter, for example, are also celebrated as public holidays. On such dates, many shops and public offices are closed. On public holidays, as well as on other important days in Finland, the national flag is always flown from buildings. In Finland, the national flag is an indication of solemnity. Thus, if you want to salute your Finnish colleagues or partners on a Finnish national holiday, you could fly their flag. If you are planning a business meeting or social event with your Finnish partners, be sure to find out in advance whether it is appropriate and whether they are available on the planned date.
On the day preceding a religious or public holiday in Finland, Finns usually work reduced hours, which means that offices close by noon. As many church holidays, such as Epiphany, Easter Monday, and Ascension Day, are public holidays in Finland, it would show consideration to schedule business meetings on a different date. Although in many other countries these dates are still regular working days, it is polite to refrain from scheduling work events for church holidays in Finland. Considering local customs shows Finns that you respect their traditions.
