The difference is that forecast trims the data to start with the beginning of the year, but feasts does not. {forecast} will always take Jan-Dec as the seasonal groups, but {feasts} will use Apr-Mar as the season when the data starts in April.
{feasts} also doesn't remove the start/end of the series if they don't exactly fit in the seasonal period (for example, partial years).
Should this behaviour be changed? My understanding is that the method isn't specific to starting at standard seasonal origins (although results will slightly differ).
Ah, ok. {feasts} is the preferable approach.
