version 4.0.3-beta generate two October about svelte-gantt

[ANovokmet]

When I removed moment from the lib, there were some issues left with timezones and headers. I'm working on it. Can you please tell me your timezone and header configuration?

[zhaofang]

timezone is UTF+8;  some configuration: rows: [], tasks: [], headers: [ {unit: "month", format: 'YYYY年MM月'}, ], fitWidth: true, columnUnit: "day", columnOffset: 1, from: moment('2021-09-01'), to: moment('2022-02-28'), minWidth: 2000, rowHeight: 30, rowPadding,

Thanks for reporting this bug, svelte-gantt currently has an issue with months because it takes a month as a 30 day duration, when it actually varies from 28 to 31, not going to be an easy fix for me, but I'll do my best

@ANovokmet Hey, I am thinking about using svelte-gantt for my project.
The correct display of month is crucial, any idea when you plan to address this issue?
I think that I could manage to implement calender weeks myself.

The display of months should be good with the last update (4.0.6 beta), let me know if it's not the case 😄

@V-Py the problem is gone for months but persists for quarters

          columnOffset: 14,
          columnUnit: "day",
          magnetUnit: "day",
          magnetOffset: 1,
          headers: [
            {
              unit: "month",
              format: "YYYY[Q]Q",
              offset: 3,
            },
            { unit: "month", format: "MM", offset: 1 },
          ],

and years

          columnOffset: 14,
          columnUnit: "day",
          magnetUnit: "day",
          magnetOffset: 1,
          headers: [
            {
              unit: "year",
              format: "YYYY",
              offset: 1,
            },
            { unit: "month", format: "[Q]Q", offset: 3 },
          ],

in the second screenshot, the two events are actually in 2022, but displayed in 2021.

Maybe reintroducing moment or something equivalent as a dependency could facilitate a lot of these calculations.
