Iterate through range and match values - google-sheets

Question

I have a spreadsheet with two sheets: Week#, Events.
Sheet "Week#" (calendar week # in Column A and the start day of this week in Column B):
01 January 4, 2016
02 January 11, 2016
03 January 18, 2016
04 January 25, 2016
05 February 1, 2016
and so on till week 52
Sheet "Events" has next columns:
Facility, Repeats, Belongs to week #, Week # starts on, Item, Action, Status.
It's filled with something like this (number of rows varies):
SalonA, monthly, 4, January 25,2016, Floor, to mop the floor, Created
The script is like this:
function createEventmanually (title, date)
{
var sheet = SpreadsheetApp.getActiveSheet();
var row = sheet.getActiveRange().getRowIndex();
var EventStatus = sheet.getRange(row, 7).setValue("Created");
var title = sheet.getRange(row,1).getValue()+" "+"Week "+sheet.getRange(row,3).getValue()+" "+sheet.getRange(row,5).getValue()+":"+" "+sheet.getRange(row,6).getValue();
var cal = CalendarApp.getCalendarsByName('RM') [0];
var date = sheet.getRange(row,4).getValue();
var event = cal.createAllDayEvent(title, date);
}
I manually copy and paste calendar dates from sheet Week# to column "Week # starts on" in sheet Events. And then run the script every time to create event.
How to automatize this process? I understand that it could be done through iteration but I cannot figure it out.
Thank you in advance.

If what you want is 52 calendar events (One every week) for every different
task in the Events sheet, this code is how you would need to do it.
function createAllEventsForTheYear() {
var allRowsOfDataInEventSheet,allDataInWeekSheet,cal,eventSh,i,j,L,Lj,lastRowInEventSheet,lastRowInWeekSheet,
lastColumnInEventSheet,lastColInWeekSh,ss,row,
weekNumberSheet,rowDataBeingProcessedFromEventsSheet,thisEventTitle,thisWeeksDate;
cal = CalendarApp.getCalendarsByName('RM')[0];
ss = SpreadsheetApp.getActiveSpreadsheet();
eventSh = ss.getSheetByName('Events');
weekNumberSheet = ss.getSheetByName('Week#');
lastRowInEventSheet = eventSh.getLastRow();
lastRowInWeekSheet = weekNumberSheet.getLastRow();
lastColumnInEventSheet = eventSh.getLastColumn();
lastColInWeekSh = weekNumberSheet.getLastColumn();
allRowsOfDataInEventSheet = eventSh.getRange(2, 1, lastRowInEventSheet-1, lastColumnInEventSheet).getValues();
allDataInWeekSheet = weekNumberSheet.getRange(2, 1, lastColInWeekSh-1, lastColInWeekSh).getValues();
L = allRowsOfDataInEventSheet.length;
Lj = allDataInWeekSheet.length;
for (i=0;i<L;i+=1) { //Loop through every row of data in the Events sheet
rowDataBeingProcessedFromEventsSheet = allRowsOfDataInEventSheet[i];//Get one row of data
thisEventTitle = rowDataBeingProcessedFromEventsSheet[0] + "Week" + rowDataBeingProcessedFromEventsSheet[2] + " " + rowDataBeingProcessedFromEventsSheet[4] + ": " + rowDataBeingProcessedFromEventsSheet[5];
for (j=0;j<Lj;j+=1) {//For every row in the Events sheet, create an event for every week of the year. 52 events for this event type
thisWeeksDate = allDataInWeekSheet[j][1];//Get the date from the second column of the data in the Weeks# sheet
cal.createAllDayEvent(thisEventTitle, thisWeeksDate);
};
eventSh.getRange(i+2, 7).setValue("Created");//I starts at 0, data starts on row 2
};
};
I have not tested this, or even debugged it, so it may not run perfectly.
