Hi, Unfortunately the ability to support multiple calendars is not currently available. We asked about this in our recent survey and while it is still on our list of things to look at, we are concentrating our attention on other features that were more popular. Jess
Ok, no problem.
I second this request wholeheartedly. It’s incredibly useful for _fantasy, science, and historical fiction_ to have the option for _multiple calendars in parallel_ (and succession, see bottom), especially when the story spans more than one locale/era tied to a particular calendar . It’s good to have the option of calendars with nonstandard time units (i.e. 1 week ≠ 7 days, 1 day≠24 hours, 1 hour ≠ 60 minutes, …), as the units of time are usually tied to some historical traditions that may not exist in other settings. Science fiction stories may want to account for different planets’ day length (Earth = 24 hours, Mars = 24 :39:35 hours); I’m not talking about including time dilation here (I wouldn’t want to touch that with a ten-foot pole), just rather the different locale/era that’s also relevant to those kind of settings. Last, but certainly not least, in historical fiction you can have easily different calendars for different locales and characters. For instance, having a story set in 1200 with a traveling or trading character may have them encounter the julian/christ ian calendar, the islamic calendar, the chinese calendar, and so on. Furthermore the _ability to transition from one calendar to another sequentially_ would be nice, for those settings that have a calendar tied to a ruler, like Japan for instance.
What I'd like to see is support for time zones, if there isn't already. (If there is I can't find it.) Many events on my timeline are relevant to characters in multiple time zones, or two events occur simultaneously, but in different time zones. Or an event starts and ends in different time zones. This makes it very difficult to accurately enter times, and using one time zone for everything (such as UTC) is not a sufficient solution.
Bumping, because this is single-handedly the most important feature for me, and heavily impacts whether I continue to use AT. Right now, I've had to kludge together a spreadsheet (see screenshot) [Spreadsheet](//muut.com/u/aeontimeline/s1/:aeontimeline:rRfY:capture.png.jpg) to keep track of dates in multiple worlds. It's klunky, it's ugly, and it takes a bit of fiddling, but it works. I'd much rather use AT to do this.
Me too. I have Earthlings, people on spaceships travelling to a new planet, and the new planet (different length of day and different length of year) that I'm trying to keep track of. Thanks zachdhunt for the screenshot. I'll use it until AT has this feature (or until I finish the book :)
If this feature is added in I will buy it immediately. It is *the* key feature that would make it worth my while to switch from my current ad-hoc setup.
Seconding this request, which is super important for fantasy timelines. Thanks in advance.
This would also be useful to me, as I have an annoying fantasy calendar I'm stuck with and would like to be able to convert between it and Gregorian easily.
Adding my vote for the multiple calendars in one timeline! I also write scifi, and I have Earthlings traveling to different planets with different calendars. My main focus is on an Earth colony on another planet who adjusted the calendar to fit their new home and started counting years from then on. It's a major pain in the neck to convert their calendar to Earth's calendar and back again! So far, that is the single most thing keeping me from buying the program. It has some really cool features that I like, but I desperately need a way to line up the two calendars!
I would like this feature to keep track of reigns of kings at the same time as I track the global era.
I also would like multiple timelines to be a feature, and I hope it comes up in the new release. I have the main world, but also places like Faery, where time is more odd, and I can't use the same dates across them both.
+1 for multiple calendar support. I am doing some historical research and have great need to see how events occur across the Gregorian calendar and other cultural calendars. Often times historical documents reference their local/cultural calendar. It would be great to use the Gregorian calendar as a reference point to see how these events overlap.
Just gonna add my support here as I've recently posted about this too
Multiple calendars would be great. I have an entire universe I want to plot on a single timeline as they are all interconnected. However they use different calendars and it would be great to see how they line up even if they have a different way of telling time
yeah, multiple calendars is important (if they can be separately toggled). My timelines want to use Western, Islamic, Chinese, and Mayan all at once!
