Date logic for cashflows
0
I have 3 dates: Present date:11/14/2018, Start of lease date: 11/8/2014 and End of lease date
and the remaining payments which is 10 payments from Present date.
Present date is always today's date. Start of lease can be anything but I am working on if the start of lease was in the past.
Based on this i have the following cash flow:
Since the lease started on the 8th, the payments will be on 8th of every month.
I have the following code that parses number of days depending on when the start date is.
function isLeapYear(year)
return (((year % 4 === 0) && (year % 100 !== 0))
function getDaysInMonth(year, month)
return [31, (isLeapYear(year) ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
function getCurrentDay(date)
var dateOfToday;
if(date && date != "")
dateOfToday = new Date(date);
else dateOfToday = new Date();
var dd = ("0" + (dateOfToday.getDate())).slice(-2);
var mm = ("0" + (dateOfToday.getMonth() + 1)).slice(-2);
var yyyy = dateOfToday.getFullYear();
dateOfToday = yyyy + '-' + mm + '-' + dd;
return dateOfToday;
function PopulateEndDate()
var d2;
var paymentDays;
var stDate;
var pDate;
if (document.getElementById("startDate"))
stDate = document.getElementById("startDate").value;
if (document.getElementById("presentDate"))
pDate = document.getElementById("presentDate").value;
var futureSDate = (pDate < stDate); //future start date
var pastSDate = (pDate > stDate); //start date was in the past
var sameDates = (pDate == stDate);
if (stDate && futureSDate)
d2 = new Date(stDate);
else if (stDate && sameDates)
d2 = new Date(stDate);
else if (stDate && pastSDate)
d2 = new Date(pDate);
else
d2 = new Date(pDate);
var dd = d2.getDate()+1000;
var mm = d2.getMonth()+1;
var yyyy = d2.getFullYear();
var today = (mm+'/'+dd+'/'+yyyy);
paymentDays = document.getElementById("paymentRemaining").value;
if (paymentDays)
var n = d2.getDate();
d2.setDate(1);
d2.setMonth(d2.getMonth() + parseInt(paymentDays));
d2.setDate(Math.min(n, getDaysInMonth(d2.getFullYear(), d2.getMonth())));
if (document.getElementById("endDate"))
document.getElementById("endDate").value = getCurrentDay(d2);
<label>Start of Lease </label> <input id="startDate" onchange="PopulateEndDate()" type="date" ><br/><br/>
<label>Present date </label> <input id="presentDate" onchange="PopulateEndDate()" type="date" ><br/><br/>
<label>Remaining Payments</label> <input id="paymentRemaining" name = "paymentRemaining" type="number" class="label1" style="text-align: right; width:80px;"> <br/><br/>
<label>End of Lease </label> <input id="endDate" onchange="PopulateEndDate()" type="date" ><br/><br/><br/>
The issue here is that I need the end date to be calculated from today's date however end 1 day before the start of lease date. In this case it parses 10 payments and the end date is on 9/13/2019.
But, it should be on 10/8/2019. Any help is appreciated. Thank you.
