If there is one prayer that you should pray/sing every day and every hour, it is the LORD's prayer (Our FATHER in Heaven prayer)
It is the most powerful prayer. A pure heart, a clean mind, and a clear conscience is necessary for it. - Samuel Dominic Chukwuemeka

For in GOD we live, and move, and have our being. - Acts 17:28

The Joy of a Teacher is the Success of his Students. - Samuel Dominic Chukwuemeka

I wrote the codes for these calculators using JavaScript, a client-side scripting language.
Please use the latest Internet browsers. The calculators should work.
Please do not put comma in any of the values.
You may need to refresh your browser after each calculation to clear all results. Comments, ideas, areas of improvement, questions, and constructive criticisms are welcome. You may contact me.
