Hi, can anyone help me with a calendars problem?

I have set up a calendar called working weeks with no holidays included, and when I go to Change Working Time and view the Calendar there doesnt seem to be any holidays in there, which is fine however, On my bar chart I put in a bar for 46wks and it comes out at 51 wks?
It also looks like there is a big gap over the weekends is this just MSP characteristic?

I cannot understand why its doing this and how I can fix this problem.

If anyone has any solutions I’d really appreciate it!

    Hi Karen,

    It could be a couple of things.

    Have you changed the standard calendar or made a copy of it? If you’re using the copy you’ll also have to change the task calendar from ‘None’ the calendar you’re using, otherwise MS Project defaults to the standard calendar.

    Have you got resources assigned to the task? If the resource calendar is different to the task calendar it could show resource unavailability as gaps in the Gantt and adjust durations accordingly.

    Most of the time this happens due to discrepancies between calendars.

    Regards,

    Darren

    Karen, Darren,
    1. when you create a new project calendar, you have to change the project calendar in Project, Project informations, not in Task informations for every task
    2. if you are using ressources, MS Project defaults the resource base calendar to Standard (or Default), whatever the project calendar is; you will change the resource base calendar in the Resource sheet
    3. MS Project only uses ONE equality between weeks/days and working hours, defined in Tools, Options, Calendar; therefore if you are using a calendar A with 5 working days a week (= 40 hrs) and a calendar B with 6 working days a week (= 48 hrs), be careful always to enter durations in days, because 1 day still = 8 hours

    Be Careful in MSP in Changing Calendars

    If Default Hrs Per Day is 8
    And The Changed Working Hour does not matches it
    there will be duration errors

    Imam,
    select the seven days of the week by clicking the mouse on every of the seven column headers (from M to S),
    then click "Non standard working time"
    change the working hours when necessary

    Hi Karen

    What on earth are you doing setting up a single activity of 48 weeks?

    No single activity should be more than 10 working days.

    Please apply bottom up planning principles.

    Best regards

    In MSP 2007, how to set all the 7 working days’ working time to 8:00-12:00 and 13:00-17:00?

    I’m tried, but one of the weekend working time keep remained as 8:00-12:00 and 13:00-14:00hrs (instead or 13:00 to 17:00hrs)

    Please help

    Thanks

    Hi Kenny

    First Check your work patterns.

    Then check any resource allocations to make sure they are on the same callendar.

    If none of that works then ditch MSP and get some real software.

    Best regards

    Or, alternatively, no need to ditch MSP.
    Use the software properly and it works.
    Ignore uninformed advice to the contrary.

    Tamara,
    setting-up a calendar in MSP 2007 / 2010 is indeed much longer than before; the plus is that your are now able to name the days off, the way Primavera P3 and PM6 and long ago Computer Associates SuperProject have done for decades;
    for sure the process in even longer in MSP; but what can we do except putting MSP aside and using some other more convenient software?

    It isn’t that much longer, e.g. a 3 weeks summer holiday is easily created by clicking on the first day in the calendar, holding "Shift" down and clicking on the last date. So consecutive non-working days are as easily created as before.

    Non-consecutive non-working days takes a bit longer to create than before, but the name could just be "x" for all of them, so e.g. making every 2nd Saturday a working day as we have on some of our projects would only take maybe 1-2min longer than before for a whole calendar-year.

    The above is valid for MSP 2010 - don’t know about MSP 2007.

    Bo,
    Calendars are 100% identical in MSP 2007 and 2010.
    It is not very long to create a non-working day in 2007 / 2010; what is much longer than before is to create a non-standard working day, say if you want to make a Saturday a working day
