Find objects between two dates along with specific time MongoDB - mongodb

I have been trying to filter all the objects which are created within a specific date range as well a specific time range.
For example: Consider the following scenario
if following are my filter's start date, end date, start time and end time.
startDate: 23/01/2015 endDate: 25/01/2015
startTime: 10:00:00 endTime: 16:00:00
So I need to filter all the objects which are created between the startDate(23/01/2015) and endDate(25/01/2015). Also the creation time should be between startTime(10:00:00) and endTime(16:00:00).
So an object which is created on 24/01/2015 but at 09:00:00 will not be filtered according to my use case.
Is there any mongo query to achieve the same where we can pass date and time separately. If not kindly suggest some workaround.

for (var d = new Date(2015, 0, 23, 10, 00, 00); d <= new Date(2015, 0,25,16,00,00); d.setDate(d.getDate() + 1)) {
var d1 = d.setHours(d.getHours()+6);
db.coll.find({createdDate:{$gte:d, $lte:d1}})
}

Add Days Google Script

I wondered if anyone could help. I have a script where I am pulling out data from a spreadsheet list, where this is a match for this week (basically an events list, to produce a weekly agenda). I will use a for loop to increment the days to add on, but I am just trying to make it work for one day for now...
The first column is the data in format dd/mm/yyy
I am trying to take today's increment by 1 and then search through the list to find a match. The searching etc, I can make work, but the date part is just not playing. I wondered if anyone could advise.
E.g. Date Column A:
06/07/2021
06/07/2021
01/11/2021
01/11/2021
01/11/2021
01/11/2021
02/09/2021
02/09/2021
var selectedDate = row[0];
selectedDate = Utilities.formatDate(new Date(selectedDate), "GMT+1", "dd/MM/yyyy");
var currdate = new Date();
currdate = Utilities.formatDate(new Date(selectedDate), "GMT+1", "dd/MM/yyyy");
var daystochange = 1;
var newdate = new Date(currdate.getFullYear, currdate.getMonth, currdate.getDay+daystochange );
Could anyone help?
Thanks
Only use Utilities.formatDate() to output dates, not to work with dates.
The JavaScript date object has all you need to work with dates and compare. When you use the Utilities function it converts it to a string, and so you lose all the functionality of the Date object.
Also bear in mind that if you have dates, that are formatted as dates in your sheet, they will automatically be returned as Date objects.
For example, if your sheet has a date in cell A1
var date = Sheet.getRange("A1").getValue()
date instanceof Date // true
Once you have your date, if you want to add one day to it, you can take an approach similar to what you have already done:
var selectedDate = new Date(2021, 1, 15)
var newdate = new Date(selectedDate.getFullYear(), selectedDate.getMonth(), selectedDate.getDate() + 1);
console.log(newdate) // Tue Feb 02 2021 00:00:00
Note - use getDate to return the day of the month, getDay only returns day of the week.
To check if two dates are the same, you can write a function to compare:
function isSameDate(a, b) {
return a instanceof Date &&
b instanceof Date &&
a.getYear() === b.getYear() &&
a.getMonth() === b.getMonth() &&
a.getDate() === b.getDate()
}
This function will return true if the dates are the same.

Convert year and month variables to timestamp in Postgresql

I have to variables: year and month, both of type integer.
E.g:
year = 2016
month = 1
I want to, in my select statement, return a timestamp given those two variables.
I've had a look at the documentation, specifically to_timestamp and to_date, but all the examples I've come across show a string being converted into a timestamp.
I do not really want to convert my year and month into a string, such as:
to_timestamp(to_char(int,year) + ' ' + to_char(int, month),YYYY/MM/DD HH24:MI:SS)
So, how can I (if it is possible) convert my year and month into a timestamp?
If you are using Postgres 9.4 or later, you could try using make_timestamp():
make_timestamp(2016, 1, 1, 0, 0, 0.0)
This would create a timestamp for January 1, 2016 at midnight. We need to specify values for the other components, even if they end up not being relevant to your query/calculation (e.g. you only need the date).

get mongodb records created in a specific month

I'm trying to get a specific range of documents, based on when they were created. What I'm trying to do is something like:
/getclaims/2015-01
/getclaims/2015-02
...
that way a user can browse through all records based on the selected month.
In my database I'm not storing a created_at date, but I know mongodb stores this in the objectid.
I found that I can get records like this:
db.claims.find({
$where: function () { return Date.now() - this._id.getTimestamp() < (365 * 24 * 60 * 60 * 1000) }
})
of course that doesn't filter based on a specific month, but only within a certain time limit.
What would be a possible way of limited a query based on a specific month, using the Timestamp from the objectid's?
I'm using mongoose, but it's probably a good idea to start in mongo shell itself.
Based on the function borrowed from the answer to this question - https://stackoverflow.com/a/8753670/131809
function objectIdWithTimestamp(timestamp) {
// Convert date object to hex seconds since Unix epoch
var hexSeconds = Math.floor(timestamp/1000).toString(16);
// Create an ObjectId with that hex timestamp
return ObjectId(hexSeconds + "0000000000000000");
}
Create a start and an end date for the month you're looking for:
var start = objectIdWithTimestamp(new Date(2015, 01, 01));
var end = objectIdWithTimestamp(new Date(2015, 01, 31));
Then, run the query with $gte and $lt:
db.claims.find({_id: {$gte: start, $lt: end}});

Change the time of a date

If I use
new Date()
it returns me date with time stamp of the current time.
How can I change the date appended with the date?
You coudl use the set method to modify your date instance:
def date = new Date()
date.set(second: 0, minute: 0, hourOfDay: 15)
If you don't need any time you could also use clearTime() to remove the time portion of your date.

Groovy get today's date at minute 00:00:00

I have this problem. I need to do the following:
get todays date
make a new date which will be today's date at 00:00:00
make another date which will be today's date at 23:59:59
For example. Today Date is 12-January-2012 19:00
How can i make a new date, which will be 12-January-2012 00:00 (the start of the current day)
It may seems easy, but i couldnt find any groovyway to get it, any help would be apreciated.
To get the date at midnight use Date.clearTime (docs):
dateAtMidnight = new Date()
dateAtMidnight.clearTime()
(Javadocs are for Groovy JDK < 2.0, clearTime() is declared void in Groovy JDK 2.0, preventing d = new Date().clearTime(). Comments indicate the original functionality may be restored, yay!)
For the comparison, instead of using <= 23:59:59, use < (the next day):
(aDate >= dateAtMidnight) && (aDate < (dateAtMidnight + 1))
An alternative way, but it sets the datetime (but it doesn't get the date merely)
dateAtMidnight = new Date()
dateAtMidnight.set(hourOfDay: 0, minute: 0, second: 0)
