Recently a client requested that we display for them a percentage of how far through the tax year we are. I did some looking online however I couldn’t find anything which suited my needs.
Below is the code I ended up writing which will calculate the percentage value and display the output at the end.
$currentMonth = date(‘n’);
$currentYear = date(‘Y’);
$dayInYear = date(‘z’);
$taxYearStartYear = $currentMonth < 4 ? $currentYear – 1 : $currentYear;
$taxYearStart = $taxYearStartYear . ‘-04-01 00:00:00’;
$taxYearStartDay = date(‘z’, strtotime($taxYearStart));
$taxDayInYear = $dayInYear < $taxYearStartDay ? ($dayInYear + 365) – $taxYearStartDay : $dayInYear – $taxYearStartDay;
$taxYearPassed = ($taxDayInYear / 365) * 100;
echo $taxYearPassed.’% of the way through the tax year’;
