[R]Generate date intervals in R

Just create a range of dates in R
Make a function

generate_date_intervals <- function(start_date, end_date, interval_days = 14) {
  # to Date
  start_date <- as.Date(start_date)
  end_date <- as.Date(end_date)
  
  # start date seq
  starts <- seq(from = start_date, to = end_date, by = interval_days)
  
  # end date seq
  ends <- pmin(starts + interval_days - 1, end_date)
  
  # to date frame
  data.frame(start_date = starts, end_date = ends)
}

e.g. df<-generate_date_intervals("2025-01-01","2025-03-31") will return a data frame like

start_date	end_date
2025-01-01	2025-01-14
2025-01-15	2025-01-28
2025-01-29	2025-02-11
2025-02-12	2025-02-25
2025-02-26	2025-03-11
2025-03-12	2025-03-25
2025-03-26	2025-03-31
