Comments on 13 Month Fixed Calendar for Android

★★★★☆ Victor Balderas · Apr 14, 2025

I like the 13th month concept. You are ahead a few days. Writing this review, and currently the app says it's on day 21 of April. When it would actually be on the day sixteen. Yes I did the comparison with the Gregorian calendar and traced back from February 2026 the following year to come, the month is a perfect alignment with the days matching perfectly. Aside from other comments editing dates and setting reminders would be an excellent edition. Keep it up! Looking forward to new improvements

★★☆☆☆ Ladislav Piaček · Oct 25, 2025

Please, if you can add possibility to set starting day of calendar from official calendar, so I can really use it then. I want to match weekdays each eyar. e.g. 30th december 2024 gregorian = 1. January 2025 in fixed.

★★☆☆☆ Tamara Rogers (Calgary) · Apr 15, 2025

I appreciate that it shows Sol, but there is zero explanation as to why it's not showing today's date. It would be nice to zoom in on a month and have the moon phases showing.

★☆☆☆☆ SageStormCloudMoonGoddess · Apr 3, 2025

I'd give it zero stars, but that's not an option. This app Does Literally Nothing except Show you an image of the Calendar. It needs to be taken down.

★★☆☆☆ RICLEY75 · Mar 3, 2025

Page looks good but 7,14,21,28 are missing in every row on every month until I turn my phone to view in horizontal view then the number come back, but also it's not on the right date and the day not highlighted on which actual day it is and more than one month has the same day highlighted, what's what, please fix I really like this concept, and your is the only of its type. It would be great to have a settings menu to change basics like to fit on phone screen
