Use calculate to return the results

Details

This function creates a complete calendar object that fills in any missing days, weeks, months, quarters, or years
If you provide a grouped object with dplyr::group_by(), it will generate a complete calendar for each group
The function creates a ti object, which pre-processes the data and arguments for further downstream functions

standard calendar

The standard calendar splits the year into 12 months (with 28–31 days each) and uses a 7-day week
It automatically accounts for leap years every four years to match the Gregorian calendar

5-5-4 calendar

The 5-5-4 calendar divides the fiscal year into 52 weeks (occasionally 53), organizing each quarter into two 5-week periods and one 4-week period.
This system is commonly used in retail and financial reporting
