3 Best APIs for Holidays in Nigeria

HebCal Jewish Calendar API is a comprehensive free API for working with the Hebrew (Jewish) calendar, providing date conversions between Gregorian and Hebrew calendar systems, Jewish holidays and observances, candle lighting times, Torah portion (parasha) schedules, and Zmanim (halachic times) calculations for any location worldwide. HebCal has been a trusted resource for Jewish communities since 1994 and serves Jewish community centers, synagogues, Jewish school platforms, and Jewish lifestyle apps that require accurate calendar data aligned with halachic (Jewish law) standards. Hebrew date conversion allows converting any Gregorian calendar date to its Hebrew calendar equivalent, returning the Hebrew month name (Nisan, Iyar, Sivan, Tammuz, Av, Elul, Tishrei, Cheshvan, Kislev, Tevet, Shevat, Adar), the Hebrew day of the month, and the Hebrew year. This bidirectional conversion supports Jewish app developers building applications that display both secular and Hebrew dates, or that calculate anniversaries according to the Hebrew calendar such as Yahrzeit (annual memorial dates) and Hebrew birthdays which may fall on different Gregorian dates each year. Jewish holiday data includes major and minor holidays across the Jewish year: Rosh Hashanah (Jewish New Year), Yom Kippur (Day of Atonement), Sukkot, Shemini Atzeret, Simchat Torah, Chanukah, Tu BiShvat, Purim, Passover (Pesach), Yom HaShoah, Yom HaZikaron, Yom HaAtzmaut, Lag BaOmer, Shavuot, and Tisha BeAv. For Jewish community organizations in Nigeria operating Jewish cultural centers or supporting the small but active Nigerian Jewish communities, HebCal's holiday data enables building community calendars that keep members informed of upcoming observances. Shabbat times and candle lighting times are calculated based on geographic location, providing the exact times for candle lighting on Friday evening (18 minutes before sunset by default, customizable) and Havdalah (the ceremony ending Shabbat, typically 42-50 minutes after sunset). Synagogues and Jewish community centers in Lagos and Abuja where Jewish communities exist can use HebCal to display accurate Shabbat times for Nigeria's geographic locations. Torah portion (Parasha) schedules indicate which weekly Torah reading is being observed in a given week, following the annual cycle of reading the five books of Moses. Jewish schools, study groups, and synagogues in Nigeria can build weekly study schedule apps or synagogue bulletin generators that automatically show the current Torah portion and related resources. Zmanim calculations provide the full range of halachic times for any date and location: astronomical dawn (Alot HaShachar), sunrise, the latest time for morning prayers (Sof Zman Tefila), noon (Chatzot), afternoon prayer window (Mincha Gedola, Mincha Ketana), sunset, nightfall (Tzet HaKochavim), and midnight. These precise times are essential for observant Jews who time their prayers and religious activities according to halachic standards, and Nigerian Jewish community app developers can provide these calculations calibrated to Nigerian cities. The HebCal API is completely free with no registration required, making it accessible to Nigerian Jewish community developers, Jewish day school app developers, and cultural organizations supporting Jewish heritage in Nigeria. The API supports JSON output format for easy integration into web and mobile applications. The HebCal API supports JSON output with CORS enabled, making it directly callable from browser-based JavaScript applications — ideal for Nigerian Jewish community websites that want to display live Hebrew calendar data without a backend server. Developers can query the REST endpoints with simple HTTP GET requests, and the well-maintained documentation at hebcal.com/home/developer-apis covers all endpoints with examples.

Abstract Holidays API is a clean, developer-friendly public holiday data API offered by AbstractAPI — a company known for building simple, well-documented API products for common developer tasks. The Abstract Holidays API provides national public holiday data for 200+ countries with straightforward API design: a single endpoint, simple API key authentication, and clean JSON responses that make integration quick and the data immediately usable. For Nigerian developers who want a polished, modern API experience for holiday data without the complexity of larger API platforms, Abstract Holidays is one of the most accessible entry points to global public holiday data. Country holiday data retrieval from the Abstract Holidays API is straightforward: pass the country code (NG for Nigeria), year, and API key, and receive a JSON array of public holidays for Nigeria in that year. Each holiday object includes the name, name in the local language, date in YYYY-MM-DD format, day of the week, type (national or observed), and a description where available. This clean, consistent response format is easy to parse and display in any Nigerian application regardless of the programming language or framework being used. Nigeria coverage in the Abstract Holidays API includes all federal public holidays, with moveable holidays like Easter and Islamic observances calculated for each requested year. Nigerian developers do not need to maintain a local database of holiday dates or write their own calendar calculation logic — querying the API with the year and country code returns the complete set of correctly dated Nigerian holidays for that year. Multiple country support in a single API account enables Nigerian businesses with international operations to retrieve holiday data for multiple countries using the same API key and endpoint, just changing the country code parameter. A Nigerian holding company with subsidiaries in Ghana, Kenya, and South Africa can build a multi-country holiday awareness system using Abstract Holidays without managing separate holiday data subscriptions for each market. Data freshness and accuracy from Abstract Holidays is maintained by the AbstractAPI team, who update holiday datasets when countries announce changes to their official public holiday schedules. Nigerian public holidays are occasionally modified by government proclamation (for example, a holiday may be moved to an adjacent Monday for a long weekend), and API-driven holiday data that is maintained by the provider requires fewer manual updates by Nigerian development teams than hardcoded holiday lists. The Abstract Holidays API is available on a freemium model — the free tier provides a limited number of API calls per month that is sufficient for small applications and development/testing. The free tier includes access to national holidays for all supported countries including Nigeria. Paid plans increase the monthly call limit for production applications with higher traffic, and pricing is affordable for individual Nigerian developers and small startups. Integration uses a single HTTP GET request with API key authentication via query parameter. The AbstractAPI documentation provides code examples in Python, Node.js, PHP, Ruby, and other languages. Nigerian developers can register for a free API key at abstractapi.com and make their first holiday API call within minutes, without setting up complex OAuth flows or SDK installations. AbstractAPI's consistent API design philosophy across its product suite means Nigerian developers familiar with other AbstractAPI products can onboard to Abstract Holidays with minimal learning curve. The same authentication pattern, response format conventions, and error handling approach used across all AbstractAPI products applies here, making multi-product AbstractAPI integrations efficient.
