Frequently Asked Questions
How do I print the calendar at the correct size?
Download the PDF and print it at 100% scale (actual size), not "fit to page". The PDF is generated at true A4 or US Letter dimensions with proper margins, so it fits the sheet exactly.
What are ISO week numbers and when should I show them?
ISO-8601 week numbers number each week of the year from 01 to 52/53, with weeks starting Monday and week 1 containing January 4. They are widely used for sprint planning, manufacturing, and shift schedules.
Can I make a Thai-language calendar with Buddhist Era years?
Yes. Switch the language option to Thai: month and weekday labels render in Thai and the year is shown as the Buddhist Era (ค.ศ. + 543), which matches official Thai documents.
Does the calendar account for leap years?
Yes. The grid is computed from the real calendar for the chosen month and year, so February shows 29 days in leap years and every month starts on the correct weekday.
