Question and Answer

Different Dates for Easter: Part One


Some years Easter is in March and other years it is in April. Why is this? Thank you.


Thank you for your question. Actually, the date of Easter is a controversy that goes back at least to the First Council of Nicaea in A.D. 325.

Two things should be noted: (1) The Western Church (Roman Catholic and Protestant churches) celebrate Easter on a different date than the date used by the Eastern Church (Greek Orthodox, etc.) and (2) some Protestants (such as the New England Puritans) did not celebrate Christmas or Easter, a conviction shared by some Protestants today in the Puritan tradition.

The Eastern Church follows the Julian Calendar (established by Julius Caesar in 46 B.C.); their Easter can be celebrated anywhere from a week to more than a month after the Western churches.

The Western church uses the Gregorian calendar, which was established in A.D. 1582 by Pope Gregory XIII as a reformed version of the earlier Julian calendar. The Gregorian calendar is 13 days ahead of the Julian calendar, which, coupled with differing definitions of a full moon and an equinox, accounts for the date disparity. (The Gregorian calendar is the one now used worldwide for civil purposes.)

Again, as I suggested above, there are as many as five weeks between the two Easter celebrations. In the Western Church, Easter falls between late March and late April; in the Orthodox Church, it is between early April and early May.

A bit strange, isn't it?

About Q&A

"Questions and Answers" is a weekly feature of the OPC website. The answers come from individual ministers in the Orthodox Presbyterian Church expressing their own convictions and do not necessarily represent an "official" position of the Church, especially in areas where the Standards of the Church (the Scriptures and the Westminster Confession of Faith and Catechisms) are silent.

The questions come from individuals like yourself. If you have questions about biblical and theological matters, you are invited to send them by e-mail by using the "Pose a Question" link on the OPC home page or by clicking here.

At least one new question is posted each week, so there should always be something new here for you to read. (For those people who would like to look at previous questions and answers, they will continue to be available as well.)

The purpose of the OPC website's "Questions and Answers" is to respond to biblical and theological questions. Matters of church discipline, disputes, or debates go beyond the scope of our work. We recommend that you present your concerns in these areas to the appropriate judicatory. In most cases this will be to a local pastor, elder, or session. We do not want the website to replace personal involvement in, or commitment to, the local, visible church.

While we will respond to every serious questioner, we are not bound to give a substantive answer to every question, should we deem the question to be beyond the scope of our purpose or our own ability to answer.

You will receive an answer by e-mail. Please be patient as many of our respondents are busy pastors. The response to your question may take up to two (2) weeks. Some of the questions submitted will be chosen to be posted here, along with the corresponding answers.

Note that the "Questions and Answers" posted on the site have been edited—all personal references are removed, Scripture references or from some source may be added, and sometimes portions are expanded—to make the questions and answers more useful to a larger audience.
