About BibleCalcs
BibleCalcs is a free set of Bible study tools: calculators for dates, reading plans, giving and measurements; a searchable Strong’s Concordance; a word-by-word reader of the original Hebrew and Greek text; a side-by-side translation viewer; verse pages for common life situations; and a handful of finders and quizzes. It is built for ordinary Bible readers, students, small-group leaders and anyone who wants a quick, plain answer without opening six tabs.
Who runs this site
BibleCalcs is run by Chris Jensen, an independent individual based in Florida. It is not a company, church or denomination, and it does not speak for any of them. Contact: rusticreckoner@gmail.com, or use the contact page.
What is on the site
- Calculators: the Tithe Calculator, Bible Reading Plan Calculator, Daniel Fast Calculator, Holiday Countdown Calculator, Hebrew Date Converter, Gematria Calculator and Biblical Unit Converter. There are also three comparison pages that set out the main scholarly positions on the date of the crucifixion, the date of the Exodus and Daniel’s 70 weeks, and a page explaining two chronology questions we deliberately do not calculate.
- Study tools: a Strong’s Concordance with 14,197 entries, an original-text reader covering all 1,189 chapters of the Bible, and a translation comparison tool for the KJV, ASV, YLT and WEB.
- Bible verses: 29 topic pages (for example anxiety, grief, courage and gratitude) plus a Verse of the Day.
- Finders: the Bible Translation Finder, Bible Verse Finder, Fasting Plan Finder, Giving and Tithing Approach Finder, and a Spiritual Gifts Finder with a sign-gifts add-on and a guide page for each of the 20 gifts.
- Quizzes: Bible Trivia, Bible Character, Holiday, Strong’s Word Study, Weekly Torah Portion and a Denomination Quiz.
What the site is not
BibleCalcs is not a replacement for a pastor, chaplain or trained teacher, and it does not give theological, pastoral, legal, medical or financial advice. The calculators are reading aids and planning aids. Where Christians disagree, such as on the dates of the Exodus or the crucifixion, the comparison pages lay out the positions side by side and do not pick a winner. Please read the full disclaimer.
Where the text comes from
- Strong’s Concordance: definitions come from the 1890 Strong’s Exhaustive Concordance (public domain), using the digitized dictionary data from the openscriptures/strongs project, which is released under CC BY-SA.
- Original-text reader: the word-by-word Hebrew and Greek data comes from STEPBible-Data (Tyndale House Cambridge / STEPBible.org), used under its CC BY 4.0 license.
- Verse pages: the King James Version text is public domain. The New International Version, New Living Translation, New King James Version and English Standard Version are shown with the copyright notices their publishers require (Biblica, Tyndale House Foundation, Thomas Nelson and Crossway), which appear at the bottom of each verse page.
- Translation comparison tool: it only uses translations that are in the public domain: the King James Version, the American Standard Version, Young’s Literal Translation and the World English Bible.
