Inthis example, we first get the current system time in seconds using time(). Then, we convert this timestamp into a string representing local time using ctime(). Finally, we print the date and time.
In conclusion, while the datetime module is the go-to choice for most scenarios, the time module and third-party libraries like arrow provide useful alternatives for getting the current date in Python. The best method to use depends on your specific needs and circumstances.
In this example, we define a function add_year that tries to add a year to the given date. If it encounters a ValueError (which happens when adding a year to February 29 of a leap year), it adds the year to March 1st of the next year instead.
In conclusion, while Python makes it easy to get the current date, you need to be aware of potential issues and how to handle them. With the right knowledge and tools, you can effectively work with dates in Python.
Mastering the retrieval of the current date in Python is just the beginning. The ability to manipulate and understand dates and times is an essential skill in many areas of programming, including logging, data analysis, and more.

The datetime module supplies classes for manipulating dates and times in both simple and complex ways. datetime.now(tz=None) returns the current local date and time. If optional argument tz is None or not specified, this is like today().
I am using a counter to make a referenz to the date position. The value is passed to a simple lua function. If the date is already saved, it is loaded from the table and if not, it is written to the datetime file and the current date is printed.
This is then interpreted as a lua-code which makes first a variable and then the value of this variable (which is the date) is printed in TeX. As long as you preserve the .ds file; your dates won't change, but let's say you lose your .ds file by mistake; there is still no need to worry. You can fool the program by writing your own .ds file and using exactly same keys in your document as argument of \adddatestamp command.
Note: Please be careful while using the names of the variables. It seems like Lua doesn't like only numeric variables. I haven't dug deep; but using \thepage instead of pn\thepage throws a weird Lua error. So better have alphanumeric variables like ds1, pn1.
Folks, I've spent over an hour (!) trying to find an answer to this apparently very, very simple question regarding Acrobat 9 Pro:
What sort of JS do I need to use to get the date on which a PDF is printed to appear as a form field in the footer (hidden normally, generated---obviously---whenever the PDF is sent to print).
I've inserted a form field (called "Today") into the footer of each applicable page, and I don't know what the right/exact/proper code is to execute a "show the current date whenever this file is printed".
I'm assuming that this code is either Custom Validation or Custom Calculation Code---either way, I feel as if I'm thisclose, but cannot close the deal.
Thanks in advance for your help. Novices like me really, really appreciate it!
Hi:
Are you following your TITLE statement with a procedure or some process that -uses- a TITLE statement??? Normally, the title statement by itself just changes the title in the SAS "holding area" for titles. You wouldn't see the results of the TITLE statement unless you did this:
Be aware that the title is somewhat misleading. That method prints the date and time the DATA _NULL_; step was run, not the "current" date and time (It was current then but may not be current when printed.). That doesn't matter much for short jobs, but can be an important difference in definition for ones that run for hours or days. Look at for an option that gets "closer" to current.
I am using a HP Laserjet 1320 printer, USB-connected to my PC with Windows 10-64 bit OS. It works fine, except that I want to configure the printer to print the current date on each document. I can't find the setting. I am using PCL5 driver recommented by Microsoft. Can someone help?
As @banhien points out, for most printers, the only really practical way to do this at present is via optional header/trailer objects set in the source document, for those applications which support such insertions.
Some printer drivers support adding the current username to the Watermark feature; a few (generally current and more expensive printers, for example Colour LaserJet Enterprise M553x) can instead use the current date and time in the Watermark:
Thanks for those tips. I want to automatically date each printout, even ones from the web, so the header/footer option in Office will not do the trick. The watermark idea is right on the money, and I am using it to date docs printed on another brand of printer. However, the Laserjet 1320 with PCL5 driver, while it does watermarks, does not include dates as an option. Is there another driver for this printer that does?
The details I posted in my earlier response about the driver options available with a Colour LaserJet Enterprise M553x printer were actually showing the options available with the latest HP Universal Printer Driver (PCL6) (version 6.2.1).
1040 form page 2 allows the preparer to enter the preparer's date of signature manually. When we print the 1040 tax return ProSeries always prints today's date instead of the date entered into the tax software. The incorrect date is used by ProSeries when printing directly to paper and PDF.
You want to put today's date in some cell? Or you wish to highlight the current date in your Excel calendar? Or you'd like to find the date closest to today? All this can be done by using the Excel TODAY function and this tutorial will teach you how.
The syntax of the TODAY function is as simple as it could possible be - it does not have any arguments at all. Whenever you need to insert today's date in Excel, just enter the following formula in a cell:
Because in the internal Excel system dates and times are stored as numbers, concatenating text with the TODAY() formula directly would result in a meaningless string like "Today is 42965". To avoid this, we nest Excel's TODAY function within the TEXT function to display the date in the desired format.
Shortcuts to get today's date in ExcelThe inset today's date as an unchangeable timestamp that won't automatically update the next day, use one of the following keyboard shortcuts:
As you already know, the main purpose of the Excel TODAY function is to get today's date. Aside from that, you can use TODAY() in combination with other functions to perform more complex calculations based on the current date. Below you will find a few examples of such formulas.
Tip. To display the calculated date correctly, set the formula cell's format to Date.Get the number of days before or after a certain dateTo calculate how many days are left before some data, subtract today's date from the future date you are counting toward:
Tip. If the result is not displayed correct, be sure to apply the General format to the formula cell.Calculate months since or before a certain dateTo get the number of months between today and a past date, use the DATEDIF(start_date, end_date, unit) function with the past date in the start_date argument, TODAY() as end_date and "m" unit denoting months:
The formulas to calculate years based on today's date are similar to the ones discussed in the above example. The difference is that you use "y" unit to get the number of complete years between today and another data:
For more information about the DATEDIF function, please see Excel DATEDIF - calculate difference between two dates.
Get age from birthdateIf you know someone's year of birth, you can subtract that year from the current year to find the person's age:
You can learn a few other age calculation formulas in this tutorial: How to get age from date of birth in Excel.
Find the nearest date to todayIf you are curious to know which date in a list is closest to today's date, use one of the following array formulas to find it out.
Note. All three formulas to get the nearest date are array formulas, so they should be completed by pressing Ctrl + Shift + Enter.How to highlight today's date in ExcelWhen working with a long list of dates or designing your own calendar in Excel, you may want to have the current date highlighted. To have it done, create a conditional formatting rule with this formula:
The detailed steps to set up a conditional formatting rule can be found here: How to create a conditional formatting rule based on formula.

Question. I am making a spreadsheet for my work and in columb B are dates, some are blank because we have not got that far. Column C is days sence column B. I use =today()-b2 for row 2 and it shows a number lets say 29. Row 3 Column B has no date yet and Column C has the formula =today()-b3 but it displays 45405. Is there a way to hide 45405 or make blank until I put a date into Column B?
