Quarter means one year divided by 4 (quartering thâ¦e year) Some companies have fiscal year not calendar year quarters. In this case, find out what is their year end date. For example, if it's fiscal year end on May 31, the first Q starts June 1 to August 31, and so on.
The 'fiscal year end' (FYE) is the date that marks the end of the fiscal year. Some companies choose to end their fiscal year such that it ends on the same day of the week each year, e.g. the day that is closest to a particular date (for example, the Friday closest to 31 December). Under such a system, some fiscal years will have 52 weeks and others 53 weeks.
