Planning around the year

Quarter one runs from January 1 to March 31, quarter two ends on June 30, quarter three on September 30 and quarter four on December 31. Payroll, tax deadlines, school terms and fiscal reporting are all built on those boundaries.

How the calendar works

The Gregorian calendar has twelve months of 28 to 31 days. A normal year has 365 days and a leap year has 366, with the extra day added to February in every year divisible by four except century years that are not divisible by 400. Because 365 is one more than 52 weeks, most dates move forward one weekday each year and two after a leap day. Weeks are numbered under ISO 8601, which starts weeks on Monday and gives week 1 to the week containing the first Thursday of January.
