always_zero_dates: Find calendar dates that are always zero or missing

In forecastsuite: Multi-Model Time Series Forecasting Toolkit and Local App

Find calendar dates that are always zero or missing

Description

Calendar dates (month-day) that are zero or missing in every year present – these look like de facto holidays/closures that were never declared, so a holiday-aware model can't account for them.

Usage

always_zero_dates(data, holidays = NULL)

Arguments

data	A tibble with ds/y columns, the finalized dataset.
holidays	Optional tibble with a ds column, the compiled holiday list – used only to flag which suspicious dates are already declared.

Value

A tibble with columns ds, flag ("Zero every year" or "Missing every year"), and declared_holiday (logical) – the undeclared rows are the actual gap.

Examples

data <- tibble::tibble(
  ds = c(as.Date("2023-01-01"), as.Date("2024-01-01"), as.Date("2023-06-01")),
  y = c(0, 0, 5)
)
always_zero_dates(data)
