• A year can consist of 52/53 weeks.
• The starting week of the year could vary depending on region,
  From moment.js documentation:

- The week of the year varies depending on which day is the first day of the week (Sunday, Monday, etc), and which week is the first week of the year.
- For example, in the United States, Sunday is the first day of the week. The week with January 1st in it is the first week of the year.
- In France, Monday is the first day of the week, and the week with January 4th is the first week of the year.

• This would mean,
  • moment.week() on the last week of December could return a 53 / 52 / 1
  • moment.week() on the first week of January could return a 53 / 52 / 1
• Currently this is not handled in the yearView and the monthView and would result in (refer screenshots)
  • yearView: last week of December or first week of January getting cropped
  • monthView: Only last week of December or first week of January is displayed rest of the weeks are cropped

Expected Behaviour

• While rendering the chart grids in chart_grid.js for YearView and monthView, add conditions to handle the following scenarios
  • last week of December could be a 53 / 52 / 1
  • first week of January could be a 53 / 52 / 1

Actual Behaviour

• Currently the chart assumes that the last week of December ends in week 52 and first week of Jan starts in week 1
