I have a column with year (2018-2019) and a column with week number (01-52). Do you know how to create two columns with information on month and quarter based on information about year and week? Example data: ID YEAR WEEK MONTH QUARTER 1 2018 1 1(Jan) 1st 1 2018 2 1(Jan) 1st 1 2018 51 12(Dec) 4th Thanks in advance!
