1. Manually Implement the Filtering (Custom Code)

You can customize the POS frontend JavaScript logic to filter categories or products by current date/time. Here's a summary of how you'd approach it:

a. Add custom fields to the category model (if not already there)

In a custom module:

from odoo import models, fields

class PosCategory(models.Model):
    _inherit = 'pos.category'

    available_from = fields.Datetime("Available From")
    available_until = fields.Datetime("Available Until")

b. Extend POS data loading to include those fields

In your POS module XML:

<field name="pos_category_ids" eval="[('available_from','<=',fields.Datetime.now()), ('available_until','>=',fields.Datetime.now())]"/>

Then ensure you load those fields in your custom JS:

odoo.define('your_module_name.pos_category_time_filter', function (require) {
    const models = require('point_of_sale.models');
    const time = new Date();

    models.load_fields('pos.category', ['available_from', 'available_until']);

    const _super = models.PosModel.prototype;
    models.PosModel = models.PosModel.extend({
        load_new_categories: function () {
            this.pos.categories = this.pos.categories.filter(cat => {
                if (!cat.available_from || !cat.available_until) return true;
                const from = new Date(cat.available_from);
                const until = new Date(cat.available_until);
                return time >= from && time <= until;
            });
        },
        initialize: function () {
            const res = _super.initialize.apply(this, arguments);
            this.ready.then(() => {
                this.load_new_categories();
            });
            return res;
        },
    });
});

2. Use a Free or Paid Community Add-on (OCA or 3rd Party)

Some OCA or third-party community modules offer this functionality. Examples:

• pos_time_restrict_category (available on GitHub or Odoo Apps)
• Custom modules developed for restaurants/cafes with time-based menus

You'd still want to vet and test these modules since not all are actively maintained.
