Hello, welcome to bad pacing.
To the current episode (18th): Six months one week (with prologue, time skip), around one month one week (without prologue, time skip), two years (flashback counted).
Planned story ending: Two to four years (real time, not counting epilogue), the story spans for >5000 years if events in the past counted.
I'm at 10 episodes (8 actual story, 2 for holiday) and they've only gotten through four days. I've been drawing this for 8 months but they haven't made it past a long holiday weekend 
In Alien Fiction, the answer is problematic. The characters are traveling at speeds which cause events to pass at different paces on their ships than outside. They have a method of marking coordinates in both time and space together in four dimensions because of how their ships move. I'll oversimplify and say it's a few days from the protagonist's point of view.
In Alien Fiction: The Queen in Yellow, 3 days.
In Soulless Saint -- which is not yet complete -- maybe a week total.
In my NaNoWriMo project, Fyberpunk, I don't know yet.
These are all novellas.
My story actually takes place over exactly around one month and over a year at the same time
It centers around a group of people trapped in one month that keeps repeating groundhogs day style, so they keep going back to the start of the month, from the outside, it's only been a month, but for the main characters, the current time is already around 64 days from the first "normal" day of the month. (although the story starts on day 32, the start of the second loop)
Revisiting this, I can actually give a rough approximation for my new series now! At the time of writing the first reply here, the D&D campaign that the comic is based off of was still going so I legitimately didn't know how much farther the timeline would go. The following month, however, the campaign ended so I have a good idea now.
From Adventure start to Adventure end, the campaign lasted somewhere around 1-2 months give or take. It's a little shaky because our DM had us fast traveling long distances at times, so I'm just estimating how long that travel would have taken by car to extrapolate that time. The campaign itself was 18 sessions with each session containing at least 1 day, but sometimes more. And then several of those fast travel segments were intertwined... and there was also a period where we kinda skipped a week so... yeah, somewhere around 5-6 weeks probably!
Around 3 years for the part I already wrote; possibly 5 years total.
But the events told are actually happening over about 40-45 years; there are full chapters of flashback to the previous generation.
The main story takes place in the span of almost a year but there are some flashbacks from 200+ years before
For story reasons, I don't think I should say the exact length, but all I will say is that it takes place over quite a short period of time!
I'd say Splitting Image happens over the course of 2-3 months, most of it offscreen though. The main events are two weeks just about, but there's a lot of downtime between the characters training, waiting for the next incident, etc.
Hmm... I hadn’t really thought about this, but from what I have planned my comic’s total story will take place over the course of five or six months.
The Turbulent March takes place over about three days. Not counting Rhunal's first day and the days she spent imprisoned.
Acolyte of the Tempest, the second Arc takes place over about three weeks.
The sequel novel, The Scouring of Refuge, takes place over a two week period. It encompasses the beginning and end of a lightning fast private war.
CELESTIALS canonically takes place about over a year. The 1st season takes place in 2-3 weeks (wildest 2-3 weeks ever lol).
Comic time is weird.
from first to 4th its about 200 years , its ongoing but between chapters can be a few days to a couple weeks. up to months
Bump my really old topic.
'Around 70 days' is what I set from start to finish.
Currently I'm on my 2nd day at early night. 
The entire season is planned to last about one week. But season 1 is like more than 100 EPs long lol.
Damn, this is an old thread :o
So, for my project - the first saga specifically, since that's the one I'm doing currently - the story time will roughly be 4 years, spanning over 5 parts, to sum it up very shortly.
For the parts themselves, they're quite varied, the first and final parts being relatively short compared to the other 3 in the middle. Part I, which I'm currently at, canonically takes place in a span of 3 1/2 months.
Parts II, III and IV don't have exact times yet, but since there's a lot of content to go with, I'll just say that II & III are the longer ones with around 1 year each and Part IV currently standing with about 6-7 months. As for the final Part V, that's gonna be the shortest with just around 3 weeks, as it currently stands.
I just love seeing my cast grow over the span of that time xP
So far:
The prologue took place over the course of like... a couple of hours. You can see the sun set and it starts going dark as it goes.
Then there's a TEN YEAR TIMESKIP 
Chapters 1, 2 and 3 happen across the course of a day. Fun fact! I had to work out what time it was because you see people's phones a few times in these chapters...
So we start with Subo at mid-late morning (around 10-ish?), and he goes looking and meets Rekki. We get a flashback to Rekki earlier that morning, showing Rekki is up and ready to work at 7.30 (god, Urien is a horrible boss, isn't he?) So she got up, went into town patrolling with her support knight, who "went for coffee", never came back and is seen handing in her resignation to Felix when Subo enters the Chapter House, leading to Felix running into the lounge a few minutes later to find a replacement and Subo getting the job.
Then after patrolling a while and beating up the studded chaps demon, Rekki gets messages from Jules...
And then after finding the anomaly and witnessing Jules' amazing application of "delicate science, and seeing the really big demon emerge, Rekki messages Sarin at...
Twelve past three.
So "book 1" (chapters 1-3) outside of the prologue (chapter 0) spans most of one day up until around teatime.
Chapter 4 starts up the following day and we know exactly when it is because good morning, Rekki!
And we're currently a number of hours later. Rekki has been to Camelot and back, Subo has gone to work and gone on an adventure with Jules and they've all driven to the University. It's afternoon now.
BUT Chapter 5 also had a lot of flashbacks, so it technically kind of also spanned ten years in a way, because we flahed back to days after the prologue, and then checked in for the following few years after it.
So in a roundabout way the answer is that Errant kind of spans an afternoon/evening and then two days, but it also spans ten years
