I have glanced through devlogs trying to figure out how to make a calendar system, but it doesn’t quite work for me. What I want to do is create a calendar to view the date. Meaning I need the day to line up with the day of the week, and I would also need it to be TextButtons. The only way I thought would be to make a calendar script with a start time of the date using os, but that didn’t seem practical. Is there a better way to go about this? Also, there are challenges like leap year.
You can actually identify when leap years occur!
Every 4 years, a leap year happens.
Every 100 years, it doesn’t happen, unless that year is divisible by 400.
I cannot code it right now, but you can try to make a system for it
- Try to see if it’s a leap year
- See if it can be divisible by 100 and 400
Ok, my biggest issue was setting up the numbers to go down the colums of the week days
Leap year shouldn’t be a problem because Roblox got the % symbol
local CurrentYear = tonumber(os.date("%Y"))
if CurrentYear % 4 == 0 then
print(CurrentYear.. " is a valid leap year")
end
Now as for checking how many months a day has, setting up a simple module script should help
local months = {
["MonthName"] = 30
}
Repeat it 12 times with the right amount of days and you should be good.
As for other stuff (such as dates and weeks), you should look into the link HellaHarrdd provided

I meant os, but I didn’t know this existed, thank you. Only one issue does this work with different time zones?
os.date("%c",os.time()) will get you the date and time like so: Tue Mar 5 01:10:35 2024
Ok, I understand that, and I used a module script and created this, but there are errors where when I go back and forth the buttons don’t load, can anyone help me out?

In the video you notice that the textboxes slowly get off kilter, and I don’t know how to fix it, so if someone could pelase help me that would be awesome!
