农历日历

一个常见的带有农历的中国日历，通常包括农历日期，节日，与节气。

关于如何绘制日历，我们可以考虑继续使用fullcalendar，我们曾经使用过一次，具体可以参考之前的文章，python绘制日历

关于如何得到农历，节日，与节气，我们可以使用lunarcalendar库，如果你不了解这个，可以看之前的文章， python使用lunarcalendar

那么现在，我们的思路很清晰了，需要将节日，节气，农历等信息，添加到日历上。

绘制日历

创建flask应用

import datetime
import calendar
from calendar import monthrange
import chinese_calendar as cc

from flask import Flask, render_template, request, jsonify

from lunarcalendar import Converter, Solar
from lunarcalendar.solarterm import solarterms
from lunarcalendar.festival import festivals


class LunarStr:
    months = ["正月", "二月", "三月", "四月", "五月", "六月", "七月", "八月", "九月", "十月", "十一月", "十二月"]
    days = ["初一", "初二", "初三", "初四", "初五", "初六", "初七", "初八", "初九", "初十",
            "十一", "十二", "十三", "十四", "十五", "十六", "十七", "十八", "十九", "二十",
            "廿一", "廿二", "廿三", "廿四", "廿五", "廿六", "廿七", "廿八", "廿九", "三十"]

    @classmethod
    def from_year_month_day(cls, year, month, day):
        solar = Solar(year, month, day)
        lunar = Converter.Solar2Lunar(solar)
        return cls(lunar)

    def __repr__(self):
        return f"LunarStr(year={self.year}, month={self.month}, day={self.day})"

    def __init__(self, lunar):
        self.year = lunar.year

        self.day = lunar.day
        try:
            self.month_str = self.months[lunar.month - 1]
            self.day_str = self.days[lunar.day - 1]
        except IndexError:
            raise ValueError("月份或日期超出有效范围！")
        if lunar.isleap:
            self.month_str = "闰" + self.month_str

    def get_calendar_date_str(self):

app = Flask(__name__)


def get_fs_dict(year):

    lunar_dict = {}

    for st in solarterms:
        lunar_dict[str(st(year))] = st.get_lang("zh")

    for fest in festivals:
        lunar_dict[str(fest(year))] = fest.get_lang("zh")

    return lunar_dict

    info = []

    for day in range(1, num_days + 1):
        lunar = Converter.Solar2Lunar(Solar(year, month, day))
        date_str = LunarStr(lunar).get_calendar_date_str()
        if str(datetime.date(year, month, day)) in fs_dict:

        info.append({

        on_holiday, holiday_name = cc.get_holiday_detail(date)
        if on_holiday:

                "display": "background",
                "backgroundColor": "#eb3152"
            })
    return info

    return info

@app.route("/")
def index():
    return render_template("index.html")


@app.route("/api/events")
def get_events():
    year = int(request.args.get("year"))
    return jsonify(add_surrounding_year(year))

添加index.html的页面

            margin: 0 auto;
        }
    </style>
    <script>
        document.addEventListener('DOMContentLoaded', function() {
            var calendarEl = document.getElementById('calendar');

            var calendar = new FullCalendar.Calendar(calendarEl, {
              initialView: 'dayGridMonth',
              locale: 'zh-cn',

              datesSet: function(info) {
                  var year = info.start.getFullYear();
                  var month = ('0' + (info.start.getMonth())).slice(-2);

                  fetch('/api/events?year=' + year + '&month=' + month)
                    .then(response => response.json())
                    .then(events => {
                        calendar.removeAllEvents();
                        calendar.addEventSource(events);
                    })
                    .catch(error => console.error('Error fetching events:', error));
              }
            });

            calendar.render();
        });
    </script>
