This may be somewhat confusing, but here it is: Printed Jewish calendars, or books that outline the order of prayers through the year, will begin with the month of 'Tishrei' ... the month in which Rosh Hashana, "Head of the Year", occurs ... usually corresponding to sometime in September. The next month ... second in the printed calendar ... is 'Cheshvan'. But the Torah refers to those months as the seventh and eighth months respectively. As far as the Torah is concerned, the first month is the month of 'Nissan' ... the month in which Passover occurs ... corresponding to some time in March or April. On that basis, the second month is 'Iyar'.
In the Hebrew calendar, the month of Nissan immediately precedes Iyar.
A Hebrew month can be 28, 29 or 30 days, so there are at least 4 weeks in a Hebrew month.
April is not a month in the Hebrew calendar, and the Sundays in any Hebrew month could easily change from year to year, just as they often do for any month in the civil calendar.
