gregorian | The tiny , composable , modular date library | Calendar library

When switching from Glue 2.0 to 3.0, which means also switching from Spark 2.4 to 3.1.1, my jobs start to fail when processing timestamps prior to 1900 with this error:

I have some data that is downloaded from a website, one column of this data is containing Hijri date. In order to have this column as proper Date column I applied the below formatting:

but the issue it will not be considered as date and be aligned to the Right unless I enter the cell (by double click or F2) and then press Enter

Because the number of rows is big the way I'm using is not practical

I tried the following:

• Copy the cells to Notepad and then paste again in excel but didn't work
• Replaced the date separator from "-" to "." and then replace back to "-" as if the date separator was "." and replaced by "-" that usually working for the Gregorian date converting it from Text to Date
• Created a VBA code applying the code for the selected cells to enter the cells and exit them to refresh, check below:

I'm looking to adjust the basic Tableau time frame from the ISO/Gregorian format to a customized one. Currently, I'm displaying data in a line chart by Month and week. The week format is based on 52 weeks ie 'Week 43' = 10/17-10/23. I would like to display the week time line relative to its given month ie the column would read October 'Week 1' = 10/01 - 10/07, 'Week 2' = 10/08-10/14 and the following month would reset the weeks to start at zero. Is this achieved by a parameter?

I have 1 nc file with a variable ppt and three dimension ppt(time,lat,lon). See below:

I am using tapkey_management_api_v1 and I need to create a grant that has recurring events for each week days. but I got an error. Is it possible to add events for each day of week?

I have a program that is meant to count a number of days that a Monday occurs in a specific range. I am having trouble updating the count through each iteration. I tried changing up the count methods even putting it in some if loops to no effect.

Current Code

I am developing an Android app for an Ethiopian company and have to deal with dates.

The calendar used in Ethiopia is similar to the Gregorian one but has two main differences: it's set approx. 7 years earlier and has 13 months. At the time I post this question the date is 13-09-2021 in the Gregorian calendar and 03-01-2014 in the Ethiopian one.

My questions are:

• does Android support the Ethiopian calendar and is it customary for people in Ethiopia to have their devices use it?

• if so, do I have to get the default formatter (that uses the default calendar: Calendar.getInstance()) in order to format the date properly?

• instead, if the device uses the Gregorian calendar how does Java support the translation to the Ethiopian date?

What would you suggest in order to simulate the full scenario, with the device set with the proper current Ethiopian date (as if coming from the network provider) and locale?

I was assigned to make a leap year calculator and as far as I can tell it is working well, however, the user is still able to input a date before 1582. I am not sure how I would go about setting a limit on the entered date. Any help is much appreciated, thank you !!

Here is my program:

I am currently implementing a calendar converter which, given a Hijri input date and time, outputs the corresponding Gregorian date and time using the JodaTime library. However, the corresponding Gregorian time is not accurate. No matter what Hijri time I input in the same day, the resulting Gregorian date is the same. This seems strange, considering that each Hijri day spans two Gregorian days, sunset to sunset, as stated in this answer (https://islam.stackexchange.com/questions/71850/can-a-day-in-the-gregorian-calendar-correspond-to-two-different-days-in-the-isla).

For example, below is the code which converts from a Hijri DateTime (current day, can specify a different time in the day) to the corresponding Gregorian DateTime:
