Hi babbar,

Welcome to this Microsoft Project newsgroup

You need to read the Help screens - search for Duration and Elapsed. In
essence, Duration is a measure of the working time between the beginning and
end of the task. Elapsed duration is specifically for tasks that are not
human oriented as it measures 24 hours per day 7 days per week - keep
elapsed times for concrete curing or paint drying types of task, and don't
assign human resources. You can also schedule in Work, eg manhours or
mandays, whence Project will calculate the Duration for you based on your
calendar settings.

As an aside, I thoroughly recommend a course on project management
techniques on which Project is based, followed by an introductory course on
Project to get you up and running quickly and efficiently.

FAQs, companion products and other useful Project information can be seen at

Hope this helps - please let us know how you get on

ElapsedTime OR Lag is esentially waiting time and is
measured in edays. If you, for example, pour concrete you
would use 2 edays for it to dry before commencing work.
Edays calculates with weekends, bank holidays etc as
concrete doesnt care less if its a weekend for it to
dry

The most important equation that you HAVE to know is
Work = Duration * Units

Lets say you have a task which is called "support". This
task is 2hrs daily for a working week. Work=10hrs,
Duration=5Days

Hope this helps
Regards
Robert

think of it another way. the tasks takes a certain time from start to finish
and during that time one or more, or even none, persons will work some part,
or all, of the time on it. a task can have a duration and yet use nil
resources, or perhaps nil work resources and some material resources.

Well, then to take babbar's question in another direction... doesn't
"edays" refer to "leveling?" Like when you choose resource leveling?
