I want the schedule of a cron job to be the las day of every month. I've used this:
<schedule>last day of month 23:59</schedule>
Is it correct?
The easiest way to launch the job at first of month 00:00. You may tweak it to run few hours before setting the <timezone> to the timezone with more positive value than the desired one. If desired timezone is GMT than you may set the timezone of the cron job to Europe/Berlin and the job will be executed last day of the month at 23:00 GMT.
As per the documentation, the format for the Cron Expression for the kind that you are trying to create is:
("every"|ordinal) (days) ["of" (monthspec)] (time)
Where:
ordinal specifies a comma separated list of "1st", "first" and so forth (both forms are ok)
days specifies a comma separated list of days of the week (for example, "mon", "tuesday", with both short and long forms being accepted); "every day" is equivalent to "every mon,tue,wed,thu,fri,sat,sun"
monthspec specifies a comma separated list of month names (for example, "jan", "march", "sep"). If omitted, implies every month. You can also say "month" to mean every month, as in "1,8,15,22 of month 09:00".
time specifies the time of day, as HH:MM in 24 hour time.
I don't think there is a direct expression for what you are trying to do.
You might need to create multiple cron expressions. For e.g. 31 of month 09:00 would address 31st day of all months at 9:00 AM and it should address all months that have 31 days and so on.

I'm struggling to format a cron schedule for gcp properly and the docs aren't really helping me out.
Cron #1: Run every 50 minutes from 11:00 to 21:00 only on the months from march to october inclusive
schedule: every 50 minutes from 11:00 to 21:00 of mar,apr,may,jun,jul,aug,sep,oct
Cron #2: Run every day at 22:00 only on the months from march to october inclusive
schedule: every day 22:00 of mar,apr,may,jun,jul,aug,sep,oct
Neither of those work, but they were one of my attempts. What am I doing wrong here?
Referring to the Formatting the schedule docs below.
There is no supported syntax for your 1st cron:
specifying minutes in an [INTERVAL_VALUE] is only supported by END-TIME INTERVAL and START-TIME INTERVAL formats, but neither of them allows specifying months in the [INTERVAL_SCOPE].
the only format supporting month specification in [INTERVAL_SCOPE] is CUSTOM INTERVAL, but that only supports day specifications in [INTERVAL_VALUE].
But you can achieve an equivalent functionality by using the finer time specification in cron.yaml and making a check for the remaining conditions inside the cron job itself, doing nothing if the condition is not met. So your 1st cron would be achieved with:
this cron.yaml entry:
schedule: every 50 minutes from 11:00 to 21:00
an additional check for the current month inside the cron job itself, doing nothing (just returning) if the month is Jan, Feb, Nov or Dec.
Your 2nd cron is possible using a CUSTOM INTERVAL, you just need to place the hour at the end of the [INTERVAL_SCOPE]. From the doc:
[INTERVAL_SCOPE]: Specifies a clause that corresponds with the
specified [INTERVAL_VALUE]. Custom intervals can include the of
[MONTH] clause, which specifies a single month in a year, or a
comma-separated list of multiple months. You must also define a
specific time for when you want the job to run, for example: of
[MONTH] [HH:MM].
So your entry would be:
schedule: every day of mar,apr,may,jun,jul,aug,sep,oct 22:00
In Brazil my payday happen on every 5th day of month.
But if the 5th day is a saturday/sunday, then the payment will happen on the 4th day.
Same if 4th is saturday/sunday: then the payment will happen on 3rd day. And so on.
Is there any way to create a event that will work with Google Calendar and iCal?
You can achieve that with iCalendar, at least as far as it concerns weekends.
Consider the following rule:
DTSTART;TZID=US-Eastern:20160505T000000
RRULE:FREQ=MONTHLY;BYMONTHDAY=1,2,3,4,5;BYDAY=MO,TU,WE,TH,FR;BYSETPOS=-1
The rule is evaluated as follows:
FREQ=MONTHLY;BYMONTHDAY=1,2,3,4,5: expand to the 1st, 2nd, 3rd, 4th and 5th day of each month
BYDAY=MO,TU,WE,TH,FR: filter by week day, retain only work days/remove weekend days
BYSETPOS=-1: retain only the last day of the set
You can verify the result at http://recurrence-expansion-service.appspot.com/
Here are the first 100 instances.
It's not possible to achieve that for holidays though.
Update:
It's actually sufficient to specify
RRULE:FREQ=MONTHLY;BYMONTHDAY=3,4,5;BYDAY=MO,TU,WE,TH,FR;BYSETPOS=-1
Since the weekend is at most 2 days long, payday must fall on one of the 3rd, 4th or 5th day of the month. Again, this does not take holidays into account.
Holidays always need special consideration. Not only does RRULE not support this kind of logic for arbitrary days, sometimes it's difficult or even impossible to express holidays by an RRULE themselves. In some countries certain holidays are always on a specific day, except when the days falls on a weekend, in which case the holiday is on the Friday before or the Monday after the weekend. Or consider the Easter date and holidays relative to the Easter date, they can't be expressed by an RRULE at all.
Not to forget that some holidays may change every now and then (like "King's days" or "Queen's days" in certain countries).
The best you can do is to manage these manually and add an RDATE and an EXDATE if payday would fall on a holiday according to the RRULE above.
I'm having a Report where I need to display the dates of last 7 days.
As shown below
Sun, Mon etc... are hard coded and the Dates are written in Expression
For example,
If today is Wednesday I need to show the Dates till last Tuesday.
If it is Thursday I need to show the Dates till last Wednesday.
How to retrieve the dates information and display below the corresponding days.
To get last seven days date you can do something like below in each expression,
To get Days in Header
=WeekdayName(weekday(Parameters!TodaysDate.Value)) --Tuesday
=WeekdayName(weekday(DateAdd("d",1,Parameters!TodaysDate.Value))) --Wedneday
Same for others too... Just by increment/decrement by 1.
To get Days Date in Data
=Format(Parameters!TodaysDate.Value,"dd-MMM-yyyy")
=Format(DateAdd("d", 1, Parameters!TodaysDate.Value),"dd-MMM-yyyy")
Same for others too... Just by increment/decrement by 1.
Here TodaysDate would be parameter date or Now() Date.
I have given demo of incremental one, you can change it as per your condition. I think you need to use decrement here. So Instead of 1 you need to use -1.
This will give you output like below,
I'm building a backend at the moment which has a number of objects which have associated dates and times, which repeat at a fixed interval, for instance:
Object 1: Repeat Weekly on Tuesdays at 17:00 UTC.
Object 2: Repeat on the first Wednesday of the month at 12:00 UTC.
Object 3: Repeat every other week (fortnightly) on Friday at 13:00 UTC from January 1, 1970.
I'm looking for the best way to represent this interval in a database, short of generating a calendar file with the object's repeating date/time info in it.
How I can set GAE cron job to run at specific date at specific time
Like 10th April at 12:20 minute.Please provide syntax for this use case.
How to set IST time zone.
From the cron format documentation:
If you want more specific timing, you can specify the schedule as:
("every"|ordinal) (days) ["of" (monthspec)] (time)
Where:
ordinal specifies a comma separated list of "1st", "first" and so
forth (both forms are ok) days specifies a comma separated list of
days of the week (for example, "mon", "tuesday", with both short and
long forms being accepted); "every day" is equivalent to "every
mon,tue,wed,thu,fri,sat,sun" monthspec specifies a comma separated
list of month names (for example, "jan", "march", "sep"). If omitted,
implies every month. You can also say "month" to mean every month, as
in "1,8,15,22 of month 09:00". time specifies the time of day, as
HH:MM in 24 hour time.
So you'd want something like:
schedule: 10 of april 12:20
timezone: Asia/Kolkata
Possible solutions:
1) Create a cronjob that runs once a minute. When the current time equals your desired time, run your code.
2) If the specific time is in the next 30 days, use a Task with the eta property set: https://developers.google.com/appengine/docs/python/taskqueue/tasks#Task
3) Use some external service to setup a webhook that gets called at the proper time, make your code run when the webhook is called.
