The Aladhan API is the most widely used free option and supports every major calculation method (MWL, ISNA, Egyptian, Karachi, Diyanet, UAQ, JAKIM, Tehran, MOON). Self-hosting a precomputed CSV from PrayTimes.js is a common alternative for sites that want to avoid runtime API calls. Either source feeds SleekRank the same way through a JSON or REST data source.

Each city row carries its preferred calculation method, so Istanbul uses Diyanet, Karachi uses University of Karachi, London uses MWL, and Kuala Lumpur uses JAKIM. The method name is rendered in the page body via a tag mapping, and the API call respects the per-row method so the times shown on each page match what local users actually follow.

Aladhan and most calculators support high-latitude rules like Angle-Based Method, One Seventh, and Middle of the Night. Store the chosen rule per row and pass it to the API or precompute script. Cities like Reykjavik or Tromso need explicit handling, and rendering the chosen rule on the page builds user trust around contested edge cases.

Either precompute the entire Ramadan month in a single source refresh before the month begins and store the grid in the row, or pull a rolling 30-day window from the API each day. The first approach is cheaper at runtime, the second is more resilient to small date shifts. Both render through the same list mapping.

Yes. Include the maghrib timestamp as ISO 8601 in the row and render a small client-side countdown component on the base page that reads the timestamp from a data attribute. The HTML body still contains the static maghrib time for crawlers, while the countdown adds an interactive layer for live users.

Yes. SleekRank registers every generated URL with the sitemap and noindexes the base template page so only city URLs get crawled. Submitting the updated sitemap before Ramadan starts gives Google time to crawl every city page ahead of the traffic spike, which is critical for ranking in a 30-day window.

Store localised strings per row for cities where Arabic, Turkish, Urdu, or Bahasa Indonesia is the primary audience. Tag mappings render the localised hero and meta description, and the rest of the page (table headers, structural copy) lives in the base WordPress page in the chosen language.

The source row stores Ramadan as a window with explicit start and end Gregorian dates, plus the Hijri year. Pages render the Hijri year in the hero and the Gregorian window in the meta description, so users searching either way land on the right page. When Ramadan spans December and January in some years, both Gregorian years appear on the same canonical URL.
