"Mortgage terms are usually 15 or 30 years.

as well as the amount of payment including interest month by month.

Martin Gardner challenges the reader to find out about something relevant in numbers
in the following paragraphs (details):

In the beginning God created the heaven and the Earth.

And the earth was without form, and void; and darkness was
upon the face of the deep. And the Spirit of God moved
upon the face of the waters.

And God said, Let there be light: and there was light.

subtracting the birthdate before 1900/1/1  from today, is shown on

So we are now at the threshold of the new millennium.  Back at the end
of 1999, we were bracing ourselves for the possibly apocalyptic Y2K issue.
Thank God, practically nothing happened.  We have weathered all that,
and now, feeling like new men and women, we are focusing on various 
challenges awaiting us in 2001.  The long-term challenge for the 21st
century would be to further spread democracy worldwide to create an
 environmentand infrastructures to enable the people on all the continents to use
 the latest industrial and information technologies to raise their living standards
 and truly civilize their societies, thus liberalizing some from poverty, racial
 prejudice, oppression of dictatorships or digital-divide.  

Now, starting to make new year's, well, new millennium's resolutions, 
we should work out our plans and schedules.

So we need the calendar for 2001 and afterword.  Don't look around for
 the calendars, though.  Here is the Excel Calendar for 2006
This has holiday
 schedule of the USA for 2006, 2007, 2008, 2009 and 2010 listed.

By entering the year, 200
4, for example, in the cell G3,
 you can have the annual calendar of that year.
Or you may find it interesting to see the current month always shown on top.
Thus we see the time really flow.  How?  Just leave the cell blank. 
- December 27, 2002 -

Then how are the holidays of the US scheduled to compare with those of
other countries such as Australia, China, Islamic, Japan, Jewish and Korea?

Are you always drawing up a monthly schedule for your
business, study or training, with paper and pens, or, well, Excel,
from a scratch.  Then, this is a template you would use Excel to print
or enter date on your PC's.  

The 3-month template version has just been revised to have a lookup
function to show the daily schedules listed on the year sheet on the monthly
sheet, for the current month and the following two months.  Here is the file

When will it be one's (oh, women's) next period in their monthly
menstrual cycles.  It is reported in an article of Time that more and
more women are tricking their bodies into skipping their periods,
some to nine instead of the usual 13 periods a year.

How then do they figure out the date of the next period, if they are to take
control of their monthly cycles.  It may be none of my business, but
I have designed a calculator on the same spreadsheet of the Excel Weeks
Calculator (cell E28), hopefully to help them get a grip on their monthly cycles.

Excel Look-up Monthly Calendar

- March 31, 2001 - The revised version of the Excel Lookup Monthly Calendar, which was
posted on June 20, 2000, has now only the daily schedules of the week listed 
on the Weekly Table shown onto the monthly calendar.

And here is one more planner.  Tired of staring at monthly calendars, I have designed
a long-term planner, a combination of a term calculator and a chart, to help work out
a plan based on To Do actions listed on the long term basis.  It is designed to show
a monthly time chart up to the year 2016.  This would help us put things into
 perspective to prioritize things to do over a given time frame.  Here is the file.
To start with, type in the starting year on the cell D7.
- June 9, 2001 -

And a weekly planner, designed to show the next 4 months, starting with the current
month (or type in any month in cell C1, eg. 2001/8), is posted.  This would
eliminate the hassle of looking up the first and last day of the month in a calendar.
Here is the file.
- June 13, 2001 -

The weekly planner is now combined with the monthly calendar
as well as 3-month calendar that shows the record marked on the year sheet,
which was posted on May 25, 2001.

On the weekly calendar, the schedule marked on the cell below
      the Monday date (eg. cell AY80) on the year sheet is shown above 
the corresponding Monday date.  

Personnel Terms & Headcount
Here is the file.
- November 21, 2001 -

On the monthly calendar, the schedule marked on the cell 2 lines below the date
(eg. cell AZ81) on the year sheet is shown on the corresponding date.

Here is the file.
- June 20, 2001 -

Here is Three Month Lookup Calendar 2002.  The 3-month and weekly 
calendars are modified to allow entry of more schedule data for each day and week

On the weekly sheet, cell C1 carries this to show the current month
followed by the next 5 months.  


Now, change this to the following:

Here in X comes any number of months before (+ changed to -) or after
the current month.

And you have cell C1 show any month to start the weekly calendar.

Excel Look-up Monthly Calendar  <I>

- June 20, 2000 -
Excel lookup function is used to show the anniversary and holiday listed on
the Annual Table, daily schedule of the week listed on the Weekly Table, 
and birthday listed on the Birthday Table,
all onto the corresponding columns of the monthly calendar (view).

- June 3, 2000 -
Staring at the calendar can be boring, unless it is one's only pastime.
I have figured out how Excel can be used to have my weekly schedule,
-- routine, that is, shown on the monthly calendar so as to avoid the hassle
of daily entry.  The look-up function is used to show the weekly events recorded
on "Weekly Table" onto the monthly sheet.
