Wrong day of the week in the near future

Hi, My novel takes place in the near future. To keep track of weekdays I have chosen 2023 in the calendar. The problem is that AT2 says that June 8, 2023 is a Friday, while other calendars think it's a Thursday. Why? Originally all events were placed in 2018, but I used Timeline -> Shift events by ... to move them first five years and then some days, so Saturday and Sunday is still a weekend (Aeon time). How can I correct the calendar to match other calendars?

Hi, I have looked at our default calendar (for example what comes with the Fiction template). It is giving Jun 8 2023 is a Thursday. Have you reordered the days of the week in the custom calendar at all? We have an issue that we are in the processing of fixing, where when you reorder the days of the week, the "first day of final era" option, which should be set to Monday for the default calendar, does not get set correctly if Monday is moved. This will change the days of the week to be incorrect. At the moment, when you are reordering the days of the week, at the end you just need to go into the Monday option and select "first day of final era". Then the weekdays will be correct. If you send your current timeline to support@aeontimeline.com we should be able to fix this for you and send it back to you. We will have a fix for this in the next update, so that if people wish to reorder the days of the week then this setting will remain with the "Monday" option unless they specifically change it. Jess

So, it's been two years....Is this ever going to be done? I have a full timeline which means I can't change this because the "first day of final era" can only be changed on an EMPTY CALENDAR. And since there also isn't the other feature you said you wanted to add to EXPORT ENTITIES I have to manually recreate my entire project. DO NOT MAKE PROMISES YOU CAN'T KEEP!

Honestly, just release the next version without the "empty calendar" lock....make it so the project has to be reopened. Warn the user to save work before continuing. It looks like those settings only affect the layout, which I get can't be changed if the project is still opened - but apps ask to be reopened after updates....it's not something new! This is the worst bug - I wonder how many people don't even know they have it, because they trust that the calendar is just accurate!

Furthermore, you might want to remove the "first day of final era" because I don't think it even does what you want it to do. On a real calendar, January 1, 0001 is a Saturday - not MONDAY! You have something wrong between 200 and 201. January 1, 200 is supposed to be a Tuesday, but it's a Wednesday in Aeon with "Monday" as the "first day of the final era". But then January 1, 201 magically corrects itself to start on Thursday. And There's supposed to be a leap year in 200, but Aeon timeline throws a fit about it. This stupid bug has me so pissed off I'm doing your work for you!

You know what. I started writing a book of how I debugged this. Aeon Timeline has so many fallacies that I'm just not even going to trust your software anymore. I have no idea why the dates are correct for my recent part of my timeline, but they are so out of wack in the past. I'm just going to use google sheets now. Have a nice day!

Your Leap Years are probablly the problem. For some reason 2/29 doesn't exist on 100, 200, 300, 500, 600, 700, 900, 1000, 1100, 1300 (If your devs don't see the pattern from that you need to fire them) 104, 108, 112 all work, but 100 it doesn't like. Compound missing leap years over a few thousand years and there is your bug!

Hi, Aeon Timeline currently uses the Gregorian calendar (the modern one used in most countries) as its default calendar, which is what is causing the discrepancies you are seeing. The Gregorian calendar has leap years every 4 years (but not every 100, except every 400), which is why it doesn't have them in the years 100, 200 etc, and why the first day of the final era starts on Monday - as this is what it would have been if the Gregorian calendar was used, and makes the modern days of the week correct. Therefore historical dates using different calendars will have slightly different days. We are planning to add more flexible custom calendars in the future so that you can create other historical calendars (such as the Julian calendar), although you still wouldn't be able to have both calendar types in the one file (eg. the transition from Julian to Gregorian calendar). This is also something we may add at a later date, however there is no uniform switch between these two historical calendars, it depends on the country and when they changed over. Jess
