Question 1

What does Holidays API by Holidays API do?

Accepted Answer

Holidays API by Holidays API (holidaysapi.com) is a comprehensive public holiday data service providing programmatic access to historical and upcoming public holidays for over 200 countries and territories, covering national holidays, regional observances, and religious celebrations from 2015 onward. For Nigerian developers building scheduling applications, payroll systems, HR software, or any calendar-aware tool, the Holidays API provides structured holiday data for Nigeria's statutory public holidays alongside comprehensive global coverage — enabling applications that must handle public holidays across multiple countries.

Nigeria's public holidays covered by the Holidays API include the 12 statutory national holidays recognized by the Federal Government: New Year's Day (January 1), Democracy Day (June 12), Independence Day (October 1), Christmas Day (December 25), Boxing Day (December 26), Good Friday, Easter Monday, Eid al-Fitr (2 days), Eid al-Adha (1 day), Id el Maulud (Mawlid an-Nabi), and Workers Day (May 1). The moveable holidays — Easter and the Islamic observances — are calculated per year based on the lunar calendar, and Holidays API provides the correct dates for each year in its database.

Payroll automation using the Holidays API is one of the most direct use cases for Nigerian businesses. Payroll software must correctly identify which days in a given month are working days versus public holidays to calculate statutory pay, overtime rates, and payment run timing. By querying the Holidays API at the start of each year, Nigerian payroll systems can populate their holiday calendars with accurate dates for all 12 national holidays — including the exact dates for Easter and Islamic holidays — without manual data entry that risks errors.

HR leave management systems benefit from accurate public holiday data for calculating available leave days, processing leave applications that overlap with public holidays, and ensuring statutory holidays are correctly excluded from annual leave counts. Nigerian HR platforms serving companies across multiple states should note that some Nigerian states observe additional state-level public holidays beyond the national list — though the Holidays API covers national holidays primarily.

Multi-country scheduling for Nigerian businesses with international operations is streamlined by Holidays API's 200+ country coverage. A Nigerian company scheduling meetings with partners in the US, UK, and Germany can query all three countries' holiday calendars simultaneously to identify dates when all parties are working — avoiding the manual research of each country's public holiday schedule that is otherwise required.

Content calendar planning for Nigerian digital agencies and marketing teams uses public holiday data to identify themed content opportunities. Nigerian national holidays like Independence Day on October 1 or Democracy Day on June 12 are high-engagement content moments that Nigerian brands reliably target with special campaigns, social media posts, and promotional offers. Automated content calendar tools can pull Holidays API data to pre-populate the editorial calendar with upcoming public holidays as content planning reminders.

The Holidays API operates on a freemium model with a free tier providing access to historical holiday data from 2015 through the previous year. Accessing current year or future year holidays requires a paid subscription starting at around $19/year — making it one of the most affordable commercial holiday APIs available for Nigerian app developers. The Holidays API historical data archive from 2015 makes it one of the longest-available datasets for auditing past payroll or scheduling decisions against actual Nigerian public holiday dates.
