About SacredCal

Many faiths. One destination. Free for everyone.

The problem we kept running into

It started with a simple question: when does Ramadan start this year? One search led to five different websites — each with a slightly different answer, cluttered with ads, and none of them telling you why the dates differed by calculation method. A second search, for Diwali, sent us somewhere else entirely. A third, for Rosh Hashanah, somewhere else again.

The information existed. It was just scattered — siloed by faith, buried under monetised search results, and rarely explained with any clarity. If you happened to follow more than one tradition, or lived in a multi-faith household, you were doing the same fragmented search every time a holy day came around.

We thought that was worth fixing.

Equal access to sacred information

There is something quietly inequitable about the current landscape. A user searching for Christmas or Easter dates finds clean, fast, well-designed results in seconds. A user searching for Eid al-Adha, Pongal, or Sukkot often ends up on an outdated page or behind a paywall, and almost never with the depth of context — prayer times, fasting schedules, calculation methods — that the occasion actually deserves.

Every faith tradition is rich with dates, rhythms, and practices that have shaped civilisations. The people who observe them deserve tools that are just as good — just as fast, just as clear, just as free — as anything available for any other tradition.

SacredCal is our attempt to close that gap. Islamic, Hindu, Chinese Lunar, and Hebrew calendars, side by side, with the same care and quality given to each.

How we work

Free, always. Every tool on SacredCal is free. We sustain the site through unobtrusive advertising. We will never put a date behind a paywall.

No account, no tracking. You don't need to sign up to use any feature. We use standard analytics to understand traffic, nothing more.

Transparent about uncertainty. Religious dates often depend on local moon sighting or community practice. Where calculated dates can differ, we say so — and we tell you why.

Respectful by default. We describe every tradition in the language that community uses for itself. If we get something wrong, we want to hear about it.
