AHC fixed date for Easter

How do you get Christians, or least Catholics and Protestants, to celebrate Easter and the feasts and fasts calculated from Easter, on fixed dates?
You'd need to start by having the weekdays happen on fixed calendar dates, for a start. So perhaps something like Tolkien's notion of having the last day of the year (and the additional day for leap years) not being considered part of the week, so that there are 364 regular weekdays and 1 or 2 non-weekly days every year.

Otherwise, it doesn't make much sense for Good Friday to happen on a Tuesday.

I mean, there's no inherent reason Christianity has to call it "Good Friday." We call it that because it falls on a Friday every year because of the way Easter works, but there's no inherent reason the Fridayness is special; in a world where Easter had a fixed date, then it would just be "Crucifixion Day" or "Passion Day" or something like that, without any mention of Friday.

That said, it would have to happen very early in Church history. I suppose you could have the Quartodecimanians win out, and then also have people still use the Hebrew calendar for liturgical purposes, which might eventually give way to it being used more generally.

True, but Easter being on Sunday is significant as that is a major reason why Sunday is the Christian Sabbath.

The tradition of Jesus being crucified on Friday and resurrected on Sunday goes back pretty much to the beginning. There's a reason most Christians worship on Sunday rather than Saturday (which was the Jewish day of rest) - because they deem that it celebrates the Resurrection. It doesn't make a great deal of sense to have Easter Sunday on a Wednesday, any more than having Good Friday moving around would. Both the crucifixion and resurrection are inherently fixed to particular days of the week.

To change this to a fixed date means either having weekdays not moving around the calendar, or rewriting pretty much the entire history of Christianity since they started switching to Sunday in the first place, and Friday was linked to that for the crucifixion.
 
Since a Pope got the calendar changed to fix Leap Year, why not a Pope or Emperor pushing through a more ambitious change and making New Year's and Leap Year inter-calendar days, allowing Sundays to always fall on the same date?

While the Resurrection happening on a Sunday goes back to the beginning, it's not the case that that was always seen as the deciding factor in when to worship. We know there were groups that continued to observe the Jewish Sabbath (i.e. Saturday), and we know that there were groups in the early church that chose to always celebrate Easter on the 14th of Nissan (choosing to emphasize the close connection with Passover instead), and that some fairly big names, including Polycarp, were among them, instead of restricting Easter to a Sunday. So it's not impossible that a different origin, while recognizing that the initial resurrection happened on a Sunday, might choose to focus on the fixed date instead.

Indeed, it has been suggested that the focus on the "Sundayness" of Easter may have had something to do with an intentional effort by early Christians to distinguish themselves from Jews (by explicitly justifying a different date to worship on).
 
Computus (Latin for "computation") is a calculation that determines the calendar date of Easter. Because the date is based on a calendar-dependent equinox rather than the astronomical one, there are differences between calculations done according to the Julian calendar and the modern Gregorian calendar. The name has been used for this procedure since the early Middle Ages, as it was considered the most important computation of the age.

For most of their history Christians have calculated Easter independently of the Jewish calendar. In principle, Easter falls on the Sunday following the full moon that follows the northern spring equinox (the paschal full moon). However, the vernal equinox and the full moon are not determined by astronomical observation. The vernal equinox is fixed to fall on 21 March (previously it varied in different areas and in some areas Easter was allowed to fall before the equinox). The full moon is an ecclesiastical full moon determined by reference to a lunar calendar, which again varied in different areas. While Easter now falls at the earliest on the 15th of the lunar month and at the latest on the 21st, in some areas it used to fall at the earliest on the 14th (the day of the paschal full moon) and at the latest on the 20th, or between the sixteenth and the 22nd. The last limit arises from the fact that the crucifixion was considered to have happened on the 14th (the eve of the Passover) and the resurrection therefore on the sixteenth. The "computus" is the procedure of determining the first Sunday after the first ecclesiastical full moon falling on or after 21 March, and the difficulty arose from doing this over the span of centuries without accurate means of measuring the precise tropical year. The synodic monthhad already been measured to a high degree of accuracy. The schematic model that eventually was accepted is the Metonic cycle, which equates 19 tropical years to 235 synodic months.

In 1583, the Catholic Church began using 21 March under the Gregorian calendar to calculate the date of Easter, while the Eastern Churches have continued to use 21 March under the Julian calendar. The Catholic and Protestant denominations thus use an ecclesiastical full moon that occurs four, five or 34 days earlier than the eastern one.

The earliest and latest dates for Easter are 22 March and 25 April. In the Gregorian calendar those dates are as commonly understood. However, in the Orthodox Churches, while those dates are the same, they are reckoned using the Julian calendar; therefore, on the Gregorian calendar as of the 21st century, those dates are 4 April and 8 May.
 
This got me thinking of a way you could adapt the 365 day calendar where you keep seven day weeks, but have each date on the same day of the week every year.

I've thought about this in the past, but my solutions always involved altering the months so that they were either 28 day months or 35 day months, with New Year's and Leap Day not assigned days of the week.

The simpler solution is to always repeat the day of the week between New Year's Eve and New Year's Day, and Leap Eve and Leap Day, so both fall on the same day of the week. So if New Year's Eve falls on a Saturday, then the following New Year's Day will also be a Saturday, with January 2nd always a Sunday, ans so on. That will ensure the next New Year's Eve and New Year's Day will both be Saturdays, or whichever day of the week you want them always to fall under.

As far as I know, no one other than me has come up with this idea, or at least its not been publicized. But have an Emperor declared that Easter would always be on a Sunday and always be on a certain date, to make the rest of the calendar work, one day a year should either be not assigned a day of the week at all, or would just repeat the day of the week of the previous day.
 
What about, a semi-fixed date: always the 2. Sunday in April, or somesuch?
this seems like a good idea.
I remember from when I used to work in retail that the... randomness... of Easter was always a hassle. Especially when Easter was late in the spring. People were wanting garden/lawn stuff, and a chunk of our seasonal counter space was tied up with Easter stuff...
 
I'm curious. Everyone talks about the Crucifixion taking place on a Friday. And yet, in most cases, where the Crucifixion is mentioned, it is spoken of as having taking place on a High Sabbath (namely Passover) not a regular sabbath. According to the Jewish calendar there are seven of these High Sabbaths scattered throughout the year, of which Pesach (Passover) is one. Add to that, Jesus mentions in Luke and in Matthew that He would spend "three days" in the Earth as the three days Jonah spent in the fish, and there is no way that you can count three days back from Easter Sunday and get Good Friday. So, if the early Church was a little more aware that it was a High Sabbath and not a regular Sabbath, it might do something about it. As to it being fixed, why not say, okay, we'll make it the first week in April or the last week of March? I'm sure they can dream up a reason why it must be fixed as opposed to itinerant (IIRC it has to do with the phases of the moon or somesuch when Easter is set).
