Bug description

We are facing an issue when using moment localizer with react big calendar on Cairo, Egypt timezone.

Issue:
On the month and week view, the date (24th April) seems to be repeating, as it is a DST change for the region.

Possible debugging:

• On trying with the other localizer like from dayjs it seems to be working fine.

Expected Behavior

Expected behaviour should ideally be no repeating dates on calendar in month view.

Actual Behavior

On the month and week view, the date (24th April) seems to be repeating, as it is a DST change for the region.
