.net core MVC Month schedule for punching in and out cant store days in database using entityframework

Question

I want to generate a view with all days of a month like this image below. https://drive.google.com/file/d/1pJvxXeajDnL7_W4VT4CNAQy_lONhRwf9/view?usp=sharing

here is my model:

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;

#nullable disable

namespace abcs.Models
{
    public partial class PunchIn
    {
        public uint Pid { get; set; }
        public int? Year { get; set; }
        public int? Month { get; set; }
        [Range(1,31,ErrorMessage ="days range is from 1 to 31")]
        public int? Day { get; set; }
        [Display(Name = "punch in time")]
        [DataType(DataType.Time)]
        public DateTime? PunchIn1 { get; set; }
        [Display(Name = "puch out time")]
        [DataType(DataType.Time)]
        public DateTime? PunchOut { get; set; }
        [Display(Name = "remark")]
        public string Remark2 { get; set; }
    }
}

here is my controller

 public IActionResult Create()
        {
          return View();
        }
    
     [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<IActionResult> Create([Bind("Pid,Year,Month,Day,PunchIn1,PunchOut,Remark2")] PunchIn punchIn)
        {
            ViewBag.Year = punchIn.Year;


            if (ModelState.IsValid)
            {
                _context.Add(punchIn);
                await _context.SaveChangesAsync();
                return RedirectToAction(nameof(Index));
            }
            return View(punchIn);
        }

here is my view:

@model abcs.Models.PunchIn

@{
    ViewData["Title"] = "Create";
}
<style>
    tr {
        background-color: yellowgreen;
        color: white;
    }

    table, th, td {
        border: 2px solid black;
    }
</style>

<form asp-action="Create">
    
    <table class="table">
        <thead>
            <tr>
                <th>
                    date
                </th>
                <th>
                    Punch in time
                </th>
                <th>
                    Puncn out time
                </th>
                <th>
                    remark
                </th>

            </tr>
        </thead>
        <tbody>
            @{
                int year = 2022;
                for (int month = 1; month <= 1; month++)
                {
                        <h2 align="center">@year @month Month</h2>
                    int daysInMonth = DateTime.DaysInMonth(year, month);
                    for (int day = 1; day <= daysInMonth; day++)
                    {
                        DateTime weekday = new DateTime(year, month, day);

                        <tr>                           
                            <td>
                                <div class="form-group">

                                </div>
                            </td>
                            <td>
                                <div asp-validation-summary="ModelOnly" class="text-danger"></div>

                                </div>
                            </td>
                            <td>
                                <div class="form-group">
                                    <input asp-for="PunchOut" class="form-control" />
                                    <span asp-validation-for="PunchOut" class="text-danger"></span>
                                </div>
                            </td>
                            <td>

                                </div>
                            </td>
                        </tr>
                    }
                }
            }
            <input type="submit" value="Create" class="btn btn-primary" />
        </tbody>
 
    </table>
</form>

When I create a form, I can't recieve day value, how to send day value to database?Thank you. In addition, I write date from Front-end view instead of using controller(postend), but is there a better way?How can I create correct days list based on select month and year in other ways with controller coding?
