文墨天机®(专业版)是集飞星、三合、四化、四柱于一身的星座易学研究者的必备辅助工具 紫微斗数，是中国传统预测学重要的支派之一，位列“五大神数”之首，通过人出生的年月日时来预测人一生的吉凶祸福。历史上，紫微斗数在民间的流传并不十分广泛，一方面是因为古代的紫微斗数预测术是皇家御用；另一方面，排盘的复杂性也极大地限制了其在民间的传播。当代计算机技术的快速发展，使原本复杂的紫微斗数排盘变的容易，在过去的二十多年间，各种排盘软件层出不穷。然而，网络上的排盘软件或多或少存在一些问题，例如：1.安星不准；2.排盘时间范围小；3.排盘方法局限于单一流派而无法广泛兼容；4.软件长时间不更新造成遗留错误无法修正、新系统版本兼容性问题层出不穷…… “文墨天机®”正是为解决上述问题而精心设计研发的一套专业易学排盘软件，服务于易学爱好者和资深易学研究者。它具备以下特点： 1. 内置高精度天文历，可排盘的时间范围大，弥补了同类排盘软件可排盘时间范围小、不便于研究古人命盘和后人命盘的缺点。 2. 支持多种系统平台，提供了一致的界面风格和操作体验，是目前业界兼容终端广泛并且实用易用的一套专业易学排盘程序。 3. 提供精心设计的排盘界面，风格简约而不简单，精心设计并优化盘面布局和配色风格，满足各层次易学研究者的使用需求。 4. 提供丰富的流派设置选项，满足不同流派易学研究者依据自身所学进行灵活设定的需求。 5. 提供方便快捷的大限、小限、流年、流月、流日和流时切换功能，大幅简化交互复杂度。 6. 提供持续的软件更新服务，广泛倾听用户的意见和建议，持续更新并改进产品已逾十年。

Calendarlog is a time management and recording app. Compared to other management apps, Calendarlog stands out for its extreme simplicity and power. And the reason behind all of this is that it is built entirely on top of the system's calendar. Leveraging the inherent strength of the system calendar, Calendarlog primarily focuses on two things: visualizing the calendar and supporting calendar entries through timing. If you're already using a calendar, then Calendarlog is definitely what you need. 1. Visualize Calendar Data: The Calendarlog app presents the data from the system calendar in intuitive line graphs, bar charts, and pie charts, allowing you to easily understand your time allocation. 2. Multi-dimensional Analysis: Based on your preferences, you can analyze data on a daily, weekly, or monthly basis, gaining deeper insights into patterns and trends in your time utilization. 3. Timing Mode: The Calendarlog app supports a timing feature, enabling you to track the time spent on specific tasks or activities by setting timers. The recorded data can be directly written into the system calendar for easy reference and management. 4. Privacy Protection: Since the data is completely stored in the system's calendar and only accessed during visualization, Calendarlog itself does not store any data. Your privacy is 100% guaranteed.
