// true if it is in last week.


$ monthRange(s : Number, e : Number, f : Number -> b) -> [b]

// Returns a range of days from 's' start and 'e' end.
// For each day apply function 'f'.
//
// Note: 's' and 'e' are not checked if they are actually in the month.
// Use `rangeInMonth` to validate those values.


$ rangeInMonth(d : Date, s : Number, e : Number, f : Number -> b) -> [b]

// Returns a range of days from 's' start and 'e' end.
// Use date 'd' to check if 'e' don't pass the last day of the month,
// if it does, return the last day.


$ beginOfMonth(d : Date) -> Date

// Returns the first day as 'Date' using date 'd'.


$ endOfMonth(d : Date) -> Date

// Returns the last day as 'Date' using date 'd'.

// Returns the begin of day as 'Date' using date 'd'.

// Generic version of the function to generate a week calendar.

// Generate a list of days from the week of date.

// Generic function to generate a continuous week calendar of 'd'.
// This function will fill the blank spaces of the week
// with the next or previous week if needed.
// Apply 'f' to each day. This function will receive the 'year', 'month' and 'day'.


$ weekC(d : Date) -> [Number]

// Generate a list of days of the week.
// This function will fill the blank spaces of the week
// with the next or previous week if needed.
