How to pass the current date to AI Assistant?

[Sergio G]

Hi,

I need the AI assistant to know which day it is when the user sents the whatsapp message.

Why? because I need to infer when the user ask for availability on "next weekend" to be able to translate to, for example: friday 12 sep 2025 to sunday 14 sep 2025

And it's specially needed when using gpt-4o-mini.

So i the AI can reply to the user's message with knowing it's timestamp could be cool.

Right now I'm trying to figure out using pabbly connect to act as an intermediary somehow.

But I think there could be a better approach.

Hello @Sergio G,

To achieve your use case, you can focus on training your assistant effectively and continuously updating the knowledge base with the available slots. Make sure the assistant is trained to recognize the different ways users may ask about availability (for example, “next weekend,” “this Friday,” “in two weeks,” etc.). If this is done properly, the assistant will be able to interpret the user’s intent and provide the correct availability information. There isn’t a need for any specific method to capture the exact timestamp of the user’s message.

Hi, thanks, but with gpt-4o-mini it keeps changing month and/or year. But the same rules with an anchor on current date worked flawlessly.

I tested on gtp-5-nano and worked well without needing to pass current date. But it's not supported on Chatflow yet.

On another example I asked how much the stay from monday to thursday and answered me:
"To calculate the price for your stay from monday to thursday I need to have the check-in and check-out dates"

And that is an example for not handling the date correctly.

Is there somehow to ask the values from custom field contact? that could do the trick and also for other things like knowing if it's local or foreign tourist

Unfortunately, we don’t have any other suggestions for the use case you are describing at the moment. It’s not possible to update the knowledge source through custom fields. If your use case is working correctly with GPT-5 Nano, you can submit a request to add this model to Pabbly Chatflow.

Thanks, I have an idea to do it, but I think they tags update is not working correctly.

The idea:
Create a Custom field for CurrentDate.

On Pabbly Connect I want to suscribe to a create contact trigger or a user starts conversation kind of trigger, or simple on a Tag applied to a contact like "update_current_date"

Then get current date using Date Filter un Pabbly Connect and update Contact custom field CurrentDate on Pably Chatflow.


At Pabbly Chatflow create a flow to trigger on CustomField update and Watch for CurrentDate.

Then add a Single AI Message with custom prompt and say something like this:

Set today to $CurrentDate and the answer the client message.

Save the answer to another custom field called "Response"

Add a message box to send: $Response, to the user.

The following is needed: how to remove a Tag from the contact? So I can delete them Tag "update_current_date"


That flow should do the trick.

Please give it a shot to understand the idea and maybe you can give me some better advice on how to do it.


I think gpt-5-nano or any model language could have the same issue.

With this trick I change the user prompt to add the current date from a custom field updated outside.


It could be so much easier if you provide a function to get the current date jeje.

Best regards

If all you want is to fetch the current date in the flow, you can add an API Request node to your flow and execute this endpoint. It will provide the current date, which you can then pass to the custom contact field.
