there’s a setting for this in p6:
1) admin menu -> admin prefs -> general tab. you can change the 1st day of the week there.
i have never fiddled with it, but i suggest you go and play.

ah – that’s not possible in p6 as far as i know.

not sure i understand? what is 1398?

how we can change types of calendar from 2019 to 1398 in primavera p6

hi khan,
p6 will only support the gregorian calendar, and not lunar or hijri, unfortunately. good question.

i have a problem in calendar ,how to change p6 calendar from gregorian calendar to lunar or hijri calendar ?

you have to go to edit menu -> user preferences -> time units tab. check on the “12 hr clock” option to show time next to dates.

thank you michael lepage sir.

hi shiva,
most users, including myself, have had 0 luck in getting p6’s shift calendars to work correctly. thus, we don’t use them. you can use stick your 24hrs working calendar and assign crews at half the normal rate to calculate the correct hours, if that’s important to you. for most, the assignment is more important than ensuring the man-hours add up. but i would avoid shift calendars and simply use the activity calendars. i hope that helps.

1) nope – resource calendar’s don’t affect activities for task dependent activity types.
2) you can’t avoid partial float or decimal float when using 3 different calendars. the decimal are created as a result of the different start or finish times during the day. it’s ok, leave it alone.
3) not sure i understand. cash flow curves plot the cash assigned to activities. activities have different calendars. i’m not clear what you’re asking.

i have three doubts in the calender

1. if i change calender’s of 世界杯时间比赛时间 in already assigned calendar whether it will reflect in the activity?
2.i have to use three calender , 7 days /8hr . 6 day/8hr, 6 day /10hr, 5 day / 8hr calender . when i am using it my float showing decimal. how i can avoid it.
3. as explaned i have to use three calender in project. but for all the activity i have to use common 世界杯时间比赛时间 cash flow . which calender i have to use. wishing your suggestion.

thank you
irshad

sorry – it’s all manual process.

you’re welcome.

the standard is to track to both. your actual progress will usually land between the early and late dates and create a banana-shaped curve. i’m not sure why you would have to revise your schedule. perhaps you can explain.

yep! we really should be able to link a global to a single corp holidays calendar. that would be a helpful feature.

hi raj,
well, i don’t know if fractional duration is acceptable or not, but it sure is confusing. having fractional duration is usually a result of calendars and lags, and sometimes progressing. i would aim to remove fractional durations if possible.

i think i might know why…i don’t think you can link a global calendar to another global calendar. i need to test it.

dear mic,

i am also facing the same problem.i want to use 2 different calendars for wbs and activities.

in all honesty, p6 doesn’t handle vacation for individuals very well. you can create a resource calendar and indicate vacation there. but then you have to switch activity types to “resource dependent” which may lead to other problems. most of us don’t track vacation or time off for individual 世界杯时间比赛时间 in p6 – it can’t really handle it properly.

i’m new to p6 and was wondering if there’s a way to account for a resource’s vacation days without having to create tasks as vacation.

any help would be appreciated

you’ll have to edit the calendar. once inside, use the workweek button to set it at 12h for every working day. but be careful! read this post first: //www.deco-dalles.com/primavera-calendars-change-durations/

my project default calendar is 7d/ 8h. i want it to be 7d / 12h and can’t see any option to do that. is there any way to do it manually?

thanks

make a udfs named “udf start” + “udf finish”.
via a global change, set “udf start” to “start” and “udf finish” to “finish”.
create a layout, showing the udf baseline vs current.
via a global change, set “calendar” to “desired calendar” and “remaining early finish” to “udf finish”.
boom – durations will fix themselves.

!!!note – check this in a copy first – not in your real project!!!

thank you mike,

what i tried to tell you is the original duration in the wbs bar calculates based on the calendar assigned to the activities. as an eg: if all the activities iin the wbs has 6 day calendar, the wbs original duration will be in 6 day calendar. if the activities are a mix of 6/7 cal. then the wbs uses project default calendar to find the original duration. my requirement is to show the original duration on the wbs based on the default calendar regardless of the calendars assigned to the activities.

once again thank you very much for your prompt response!

amjad,
ignore the calendar in the wbs bars – calendars are not assigned to wbs – only to activities – what you see is a product of change the calendars and the group bars not having the time to catchup. this will either fix itself automatically – or you can refresh the screen with f5.

is one of these activities a milestone?

hope all is well with you. i am facing below problem while preparing the program in p6.

successor activity showing same start date as predecessors finish date despite having finish to start relationship.

appreciate if you help me to sort out this issue.

my project default calendar is a 7 day calendar. the wbs calendar is rolling up and uses 6 days calendar since all the activities underneath the wbs uses 6-day calendar. how can i show a 7-day calendar in the wbs summary ?

hi denis,
that’s the correct approach – you can have different calendars in your baseline than in your current schedule. you might consider creating another baseline based on the new version of your schedule with the calendar change as well. you may need it going forward.

one question: is it possible to use 2 different calendars for the baseline and for the current schedule? what has happened is the working hours have changed completely since the bl was approved, so now we have 12 hours a day with no weekends/holidays, but in the baseline we have 8 hours a day with weekends and national holidays off.

my intention is to use 2 different calendars for my bl and current schedule – is my approach correct?

the explanation given here is very helpful. thank you
i have a query here, what happens if i assign one calendar to my project where every monday is a holiday. but i assigned an another calendar to my activity where sunday is a holiday. so, can you please explain how this scenario works in p6?

to clarify, you’re setting a default calendar for the project by finding the project on the project screen, going to the defaults tab and setting the calendar there – right?
if you have an blank project, then yes, all activities will get the default calendar. but if you have activities in your schedule, making this change will not change the calendar for all activities that already exist. you must perform a fill down to do that.

varun.k.gupta.

damie,
i suspect you a falling into the trap of trying to force dates and times. this approach isn’t recommended, but often if we’re not familiar with p6, we try it anyway. forcing activities to start on a specific date or time should not be done – unless it’s a one-off case and then you can use a constraint to hold an activity to a date / time. you want p6 to figure out the scheduling for you – you set activities and durations, and link them together. tap f9 and all of the dates/times are calculated for you. then you can adjust a few activities with constraints.

de nada. por favor, sigue leyendo!

hi jaff,
i would err on the side of using the calendar that is used mostly throughout. for example, if you have design work on an 8hr calendar, and construction work on a 12hr calendar, i would probably use the 12hr calendar as the default project calendar. it pays to be cautious and to continually audit your activities to ensure you’re using the proper calendar.
michael

when you are using multiple calendars in your schedule, which calendar to be used as default calendar at the project level?

another problem is that i add the risk of the project when i enter the value of the impact it not allow to me , such as labor unit, material unit etc , how i enter the value of impact?

i think you want this setting : admin menu -> admin preferences -> general tab. there’s a setting for the first working day of the week.
m

steve, check the calendar used to calculate lag. hit f9 -> options button. at the bottom look for the setting “calendar for scheduling lag”. what is it set to? predecessor calendar usually works for most situations.
m

ratan,
goto edit -> user preferences -> time units tab. use the dropdown called “durations format” to select days or hours or something different.

i do not know why you think that the float is not being calculated correctly when using multiple calendars. can you show me an instance where this is the case. i would also have to see the working hours for each calendar to perform a hand calculated forward and backward pass. i would also have to know of any constrained dates in the schedule and the project must finish by date and the data date.

i’m not really aware of this issue. what’s your experience?

sir plz give procedure for how to l earn that primavera software. its very essential for my m.tech project…help me

zoltan & dalal,

for project’s total duration to be in calendar days; i suppose you should just change the project’s default calendar (if using p6v7 or lower) or change the global default calender if using version 8. in any case, zoltan’s work around is brilliant 🙂

my problem is the value of duration and total float are contained a decimal number and i’ can’t avoid that .

many thanks,
gad

thnx for the article its very usefull , but i have one question …. there is aproblem which i face all time when i use 2 or more different calendars in my schedule for the same project ..it is the total duration for the whole project “calendar days” in th wbs summary row ?!

thanks for the detail explanation.
could you please tell about shift calendars, how we use this calendars in p6.

regards,
mikayil
