Answer 1

试试这段代码。今天的日期是x

var x = new Date()
x.setFullYear(x.getFullYear()+1)
x.setDate(x.getDate()-1)
console.log(x);

Answer 2

这是你的代码。只需运行代码并查看答案

<?php
$StaringDate=date('Y-m-d');

$newEndDate = date("Y-m-d", strtotime(date("Y-m-d", strtotime($StaringDate)) . " + 1 year"));

print('Next Reminder Date ' . date('Y-m-d', strtotime('-1 day', strtotime($newEndDate ))));

?>

Answer 3

令人惊讶的是，我的工作时间比我应对的时间长一点。

我参与了“下次续订”和“提醒”日期（看到它需要在评论续订前15天）

Fiddle

$("#datepicker3").datepicker({dateFormat: "mm/dd/yy",});
$("#datepicker2").datepicker({dateFormat: "mm/dd/yy",});

function pad(s) { return (s < 10) ? '0' + s : s; }

$("#datepicker").datepicker({
    dateFormat: "mm/dd/yy",
  onSelect: function(dateText, instance) {
        d2 = $.datepicker.parseDate(instance.settings.dateFormat, dateText, instance.settings);
        d2.setDate(d2.getDate() - 1);
    d2.setFullYear(d2.getFullYear() + 1);
    //alert(date2);

    d3 = $.datepicker.parseDate(instance.settings.dateFormat, dateText, instance.settings);
        d3.setDate(d3.getDate() - 15);
    d3.setFullYear(d3.getFullYear() + 1);
    //alert(date2);

    date2 = [pad(d2.getMonth()+1), pad(d2.getDate()), d2.getFullYear()].join('/');
    date3 = [pad(d3.getMonth()+1), pad(d3.getDate()), d3.getFullYear()].join('/');
        //alert (date2);

    $("#datepicker2").datepicker("setDate", date2);
    $("#datepicker3").datepicker("setDate", date3);
    }
});
