13 Month Fixed Calendar

About this app

The International Fixed Calendar is a calendar system where every year aligns with the same days of the week and dates, ensuring consistency in weekly patterns. It was first proposed by Moses B. Cotsworth in 1902. This calendar divides the year into 13 equal-sized months, each consisting of 28 days, resulting in a total of 364 days. Leap years are calculated similarly to the Gregorian calendar, with an additional day added every four years. However, in the International Fixed Calendar, the extra day is inserted between June 28 and July 1, known as "Sol," effectively creating a 365-day leap year.

While the month names align with those of the Gregorian calendar, an extra month called "Sol" is inserted between June and July. This arrangement starts each year on a Sunday and ends on a Saturday, ensuring that the first day of each month falls on a Sunday and the last day on a Saturday. This consistency aids in planning and daily routines.

The International Fixed Calendar enhances calendar consistency by ensuring that the same dates align with the same weekdays each year.

Ratings and reviews

I've been looking for an app like this for a while now. Though, if it's possible, I would love for the developer to add 3 features to it if it's possible. 1. Allow for users to change the names of the months. 2. Allow for users to mark dates on the calendars. 3. When a date is marked, the user can write on and save a pop up note explaining the occasion.

well its a good app idk how it doesnt have any reviews yet theres some things i think should be improved like the days(m,t,w)should be added for convenience and the month names should be renamed to the previous ones like july and august were named after julius and augustus..so they shouldnt be included in the 13 month real calendar like the dec means the 10th month etc. also a switch option for those who prefer the july aug and those who prefer real month names cnt typ mor wanted to sugst more

latest update doesn't show day of the week anymore 🤔.it would be nice to have a feature to put reminders on days, meetings just like any other calendar
